REVIEW: Exposure Lights Strada Mk 6 (2016)


Bathed in red: Startline, 2015 Rapha Manchester2London
We're an Exposure household, you might say -

Exact burn time left. No more 'range anxiety'

Exposure Lights Strada Mk 6 (2016)

Lighting. Come late August, a night out in London and oops...no lights and a self-conscious flit home, 'hypocrite' branded across my conscience. I'm not too sympathetic for riders who don't bother with lighting.

This year was a bit different. September 6th was the Manchester2London ride, put on by Rapha to raise money for Ambitious about Autism. So I had an early foretaste of the winter riding that lies ahead. It was a gorgeous day of sun and light wind. But it began and ended in the dark as all epic adventures should.

I noticed a lot of miniscule lights around the field of 200+ riders, saving weight and bulk, but also some impressive stuff. One abiding memory was racing the last leg from Hertford to the Olympic Velodrome in East London. There was a point when we put our lights on, but then another point when nightfall became a reality. We hurtled into a black wood, but the guy in front of me had an Exposure Sixpack, surely one of the ultimate lights money can buy, with a 'Wembley effect' 2,000 lumens. I just followed him. I could see every pot hole and it wasn't even my light.

My choice of weaponry was an Exposure Flash on the front, and a Flare on the back tucked in beautifully under the saddle rails using Exposure's saddle rail bracket (£7.95). The Flash functioned only intermittently despite me deploying a fresh, spare battery I'd carried since Manchester! So I have now bought a Mk 6, 2016 model Strada, a big step up and a chance to conduct a test over the next couple of months.

I'm planning to include some night riding, the usual epic amount of London commuting and some Audax. So far the Strada looks like a huge advance, with precise burn times relieving much anxiety. But the niggly question I've got is whether it is better or worse than a Sixpack. I've got a Sixpack. The argument for it is that it's a nuclear weapon that brooks no argument. The argument against is that it's comparatively bulky, too heavy for club riding, and so bright that in practice you run it on low beam 99% of the time. If you mount it at the wrong angle you blind drivers to the point where you attract nothing but pure aggression. So arguably it's overkill...except that I love it, especially when conditions are terrible and you want to be lit up as much as possible, or in the countryside when actually, yes, you have to light up that lane and read the potholes.

REVIEW: Schwalbe Durano Plus tyre

Front tyre showing bald centre line
REVIEW: Schwalbe Durano Plus tyre, 700x23c Road, folding
This review is a 'whole life time test,' not what you normally get from Bike Radar et al. I noticed lots of confusion and gallows humour on forums about the acceptable life of a tyre. Unlike cars, there is no legal minimum with bike tyres. On one forum, the first advice was: keep going until you can see the inner tubes. Someone replied: if you're fifty miles from home at that moment, good luck!
Here's my experience.
I fitted these Durano Pluses on my commute/winter Enigma in December, 2013. They have lasted 8,500 kms. I hasten to add that they could have done more, at least a bit more. Let's say 10,000kms - maybe. But I decided to call it a day. Here's why. (1) I noticed that a new 'centre line' had become visible when it had never been before, a sign that the main tread is almost gone through. Don't be fooled by the crosses down the side - that's not where all the work is being done. Secondly, both tyres, but especially the rear, had 'squared off'. I commute all over London with heavy Ortlieb's, every day, and have also used the bike for long distances in all weathers over two winters. The rear tyre took an absolute battering. London is an incredibly abrasive environment, as these photos show. But hey: not one single puncture throughout the test, which is a remarkable testimony to how tough the Pluses are.
The final photo shows you what keeps the glass and flints at bay, the blue latex layer that lies beneath. I did that on the final day, when I knew I'd change them over to new ones. I locked up on Highgate Hill and held the tyre in one position for a thirty metre skid.

Why Change? I could have carried on. But these comparatively slow tyres had gone 'slack'. Without panniers, on a 125km ride last week, the back tyre in particular felt draggy and 'flat', no doubt a result of the squaring off. It felt baggy. Had I been on a world tour, I might have just kept plodding along, but I enjoy my riding. There are limits between parsimony and pragmatism.

Verdict.
These are the best tyres I have ever used for industrial, non-sporting use. In 700x23 guise they weighed 300g, 40g LESS than the claimed weight of 340g. When I demounted them, the rear weighed 250g, the front 270g, the amount of lost rubber! OK, they are rubbery feeling, compared to the beautiful feel you get from a Conti 4 Seasons or Durano S. But it means you can commute fast, with laden panniers, and not worry. I'd also add, perhaps above all else, that the wet weather grip is far, far better than you'd imagine. I once mounted a Marathon Plus. Now that's a wired tyre, and will go 20,000kms, but the penalty in wet conditions and rolling resistance is a stiff one. Woe betide you if you corner on a wet drain cover. That's not the case with the Durano Plus. It grips far beyond what you'd expect from a 'hard' compound. As the Velominarti chaps point out in The Rules, a motorbike tyre for racing will last one race. If you get anywhere near 10k kms out of a bike tyre, count yourself lucky. For race tyres (sub-200g), I reckon on one season maximum, which might only be 2-3000kms.

Pock marks no object but show how abrasive it is

More of the same: front tyre

Profile significantly squared off, rear tyre

The latex under the skin. The tyre could have gone on.

BOOK REVIEW: Roads were not built for cars

BOOK REVIEW: Roads were not built for Cars by Carlton Reid (2014)

BikeBiz (www.bikebiz.com) founder Carlton Reid has published an extraordinarily timely and valuable book.

The rhetorically charged title unfolds in two respects. First, the art of road building enjoyed a pre-railway peak in the 1830s. So in that sense, roads were built for pedestrians and horses and stage coaches. Reid's second point, and the central theme of the book, is that the coming of the bicycle from the 1860s, and its bona fide 'craze' period in the 1880s and 90s, resulted in myriad road improvement lobbying in Britain, in Europe, and in the USA. This lobbying was carried out by cyclists and pre-dated the motorcar. It's a Very Important Fact. Hence the first half of the sub-title of the book, 'How Cyclists Were the First to Push for Good Roads.'

The second half of the sub-title reads, '...& Became the Pioneers of Motoring.' This is where Reid's narrative gets delightfully confounding, if you are a partisan of cycling, and not just in the ordinary (and perhaps obvious) sense that numerous cyclists became motorists, and are today both at once. More pertinently, it was the most vigorous cyclists who became the most vigorous motorists. Reid offers cameo histories of 60 pioneering car manufacturers with cycling roots. It wasn't just the (slightly) better known handful of examples such as William Morris in Oxford, and Carl Benz in Germany.

The central reason for this organic transition was technology. The Victorian bicycle craze was a feast of rapid innovation comparable to mobile phones a century later. As Reid painstakingly recounts, it was the bicycle that delivered pneumatic tyres, ball bearings, differential gears, roads, motoring and even aviation (consider the Wright brothers and their roots in cycling).

The great cycling pioneers of the late Victorian period saw themselves as red-hot progressives. What the car and the bike shared in common was the open road and freedom from timetables, plus the adrenalin of speed and the utility of getting from A to B. This commonality was embodied in the tellingly titled groups such as the Self-Propelled Traffic Association.

As the book unfolds, however, we get all sorts of dark portents concerning the future dissociation of the two pursuits of cycling and motoring, and indeed their eventual mutual antagonism despite what they held in common. For one thing, the bike and the car impart to the operator a sense of being the author of propulsion. But while the car magnifies that sense to almost monstrous levels of capacity, it is a sleight of the right ankle, so to speak. The driver is a facilitator but not in fact the author of anything. The cyclist, by comparison, is the engine, and in many respects the suspension as well. Chapter 5, Speed, is exceptionally good at distilling all this. Early cycling purists were extremely aware of the nuances and distinctions. They already knew in their Victorian bones that the car would result in terminal boredom on the M4 and the larding effect of too many unearned Greggs sausage rolls, but they also delighted in mechanical efficiency and in progress and in speed. Many of the pioneers of cycling became advocates of motoring when there were only a handful of cars and no climate change. Even then, they knew that each pursuit was different and a few saw that the car could lead to all sorts of mischief. Not a few of them were killed by cars, while cycling. As the car took off the bike began to fade.

Actually, that last bit is wrong. The bike didn't fade. It did something much more damaging to its image in a world (especially in Britain) blighted by wretched class division. It went main stream. As the bicycle became affordable to workers, so the rich and privileged switched over to cars. By the 1930s, when millions cycled to the factory gate, the elites (whether true Aristocrats or middle classes) had typically disowned their earlier zeal for two wheels.

Of course, at the end, Reid brilliantly (if briefly) brings to bear our own, twenty-first century reversal of the mid-twentieth century, suggesting that since the same millions of blue collar workers ascended to car-dom (in the fifties, sixties, seventies and eighties), gradually it again became chic and even elite to be seen in lycra on a swanky carbon fibre scorcher. The arrival of Rapha and Team Sky, in this light, is not a coincidence, but nigh on inevitable in a society driven still by privilege, elitism, material display and so forth. Cars became prole-mobiles. Bikes are the new elitism. Another slightly discomforting point for partisans.

Speaking for myself, as a journalist who has written lovingly about fast cars and fast bicycles, and indeed their slower brethren, I found the book therapeutic as well as fascinating. I've always owned a discomforting sense of not knowing which tribe I belonged to exactly, yinning and yanging between them, but ultimately knowing I was more cyclist than car guy (but you wouldn't always know it). I published a humourous piece about pro-cyclists at the wheel of cars in the Daily Telegraph Motoring Section on the occasion of the 100th Tour de France. This predated Roads were not built for Cars but made a similar point, that it is a modern myth to say or believe that cyclists and motorists are separate groups, even though they often behave like it on our busy roads.

What I found most engaging about Reid's research, is just how much it brings to life the late Victorian pioneers of cycling. Those pioneers no longer seem like whatever fusty impression you have of the dread term 'Victorian'. They come alive as the Google and Apple innovator-equivalents of their generation. They are zingy and close and alive. The ugliest and dullest bits of the past century come across rather as the mid-twentieth century and the sixties, when the planners fell in love with concrete and peer-presided traffic consultations tried their hardest to write the cyclist out of existence (except in the Netherlands, where apparently cycling was wrapped up in national character - a subject I'd like to know more about).

My follow-on thought from Reid's book is that what we now need is a massive investment in light rail, trams and trolley buses, all the things that catered to the non-cyclists of the late nineteenth century before cars came along to tempt them. Cars will no doubt continue, but road-as-race-track needs to become track-day-only; driverless electric and hybrid cars will take over the public highway, slashing fatalities and injuries, and cities will become largely car free centres of utility cycling and public transit. Cyclists will be subject to further restrictions such as speed limits in Royal Parks, if I am not mistaken, in light of their 'scorching' habits and the typically-forgotten rights of pedestrians. Cars will be banned from those same parks, except for special user groups such as the disabled.

Far from being a slender insight banged out into the Twittersphere and blogged about the land, Roads Were Not Built for Cars took Reid four years of graft, as 500 pages of careful historical research does. In fact it's a marvel that he did it in so little time. Deeply grateful to Carlton Reid! Published for now as an e-Book in numerous formats, following a tiny print run last year that sold out quickly, the book will be published in hard and soft back later this year. If you want the full beans, the print version will be worth waiting for because it will include the full index and over 900 footnotes, all missing from the otherwise delightfully executed iBooks version (which in turn boasts photo galleries and audio-visual elements that you can't get from print).

REVIEW: Atomic22 security skewers, seat post clamp, saddle bolt, stem bolt

REVIEW: Atomic22 security skewers, seat post clamp, saddle bolt, stem bolt

Tribe set H plus a ti saddle bolt for a Brooks Swallow
In my last blog I narrated my visit to UK-based Atomic22, whose sole business is making extraordinarily high quality bicycle security components using a unique, 3D key.

Exactly a week later I returned to Patrick Wells and his business partner Ayantika Mitra to pick up and install the goodies.

What you see here is what Atomic22 sell as a skewer set called Tribe, version H, which retails within the EU for £153 (deduct 20% VAT outside EU).

The only extra is the additional titanium bolt pictured next to the seatpost clamp, which is to replace the allen key bolt attaching my Brooks saddle.

The purpose of installing this little feast on my newish Enigma, is to foil thieves in London.

Installation is relatively straightforward if you are already used to sorting basic bike maintenance. You need to purchase for an extra tenner the Sealey, Micro Ratchet Bit Driver that Atomic 22 sells (they intend to make their own one day), and a torque wrench is a very good thing to have to hand if you don't already have a feel for the difference between 2 Nm of torque and 10 Nm of torque. The only glitch we encountered concerned my stem cap, but this reflected a poor trim of the existing steerer, not the Ahead Stem cap supplied by Atomic22. We resolved it by adding 1mm to the spacer stack height, to ensure that the bolt was tensioning the headset bearings correctly. If in doubt, a good mechanic would help you do all this. Hand them the extremely precise Atomic22 instruction manual and let them get on with it. Any club rider or seasoned commuter will be fine on their own.

Will these components do the trick? I have complete confidence, simply in the sense that there are so many less-well protected bikes for a thief to move on to once they encounter Atomic22 and get confused. It starts with a magic, computer-generated, many-digit number that is the code for a unique, 3-dimensional key. A CNC machine converts this code into metallic reality, using a mixture of titanium and stainless steel depending on the part. Beyond the magic of the formula, Atomic22 have also subjected the parts to all sorts of nasty, down-to-earth attack sequences by burly ex-bike thieves and ex-strong men wielding hammers and chisels and goodness knows what else. It's not just pretty stuff on paper and in the lab. They have blocked the insertion of a slim or sharp implement that can be levered or twisted, a weakness of some rival products.


Skewers from stainless steel; bolts from aerospace grade 6AL 4V titanium. Beautiful.
Obviously, I cannot comment directly on the strength of these parts subjected to attack, because I don't have access to the right sort of laboratory. But the quality of the manufacturing is completely evident from the first glance. Patrick explained how murky the global supply chain is for titanium, to cite one instance of his fastidiousness. Within the top grade, grade 5, there is still a world of difference between a batch of the metal coming from a Chinese mill, and one coming from the States, he tells me. He was once in receipt of a funny batch and returned it immediately. Since then, he has gone so far as to specify the exact mill from which he'll accept shipments. That's exactly the sort of perfectionism we appreciate.

It would be crazy not to mention the aesthetic delight of these parts. They look great displayed in the box, and they look just as good when mounted. They remind me of the skewers supplied with my first ever pair of ZIPP 303s. Fantastic quality.

It would be equally crazy not to pick up on the weight weenie aspect. Atomic22 skewers weigh approximately half the weight of Shimano Dura-Ace. Yes, you have to carry a small bit driver and the key with you, but most riders are carrying an equivalent multi-tool anyway. We weighed the Atomic 22 skewer at 57.4grams. Dura-Ace comes out at 99 grams. The difference is because Atomic22 skewers are butted and don't have chunky quick-release levers. This is all nice-to-have even if the first application is less likely to be a racing situation (although such riders are buying them in droves I hear - these high end wheels we're all buying are vulnerable).

Do the skewers represent value for money? It all depends on your bike, but there are few wheelsets that cost less to replace than the Atomic22 skewers that mean they won't need to be, quite apart from the inconvenience. They cost less than most dedicated bicycle insurance policies, which is going to sting you if you live in a high-theft post code as I do. For less than one premium you have hardware that will last for years, so I consider them extremely good value.

Criticisms?
Arguably, Atomic22 should provide two 'keys' rather than one (although spares can be purchased). I'd also like to the see the key drilled through so I could attach it to a key-fob for safe-keeping. And the shaft of the key might be recessed to take an allen key so you have the option of using a multi-tool rather than the bit-driver. As it stands I am terrified of losing this tiny bit, even though Atomic 22 have the magic number stored against my personal details.

Summary
The overwhelming impression I have is that these guys have Chris King levels of engineering perfectionism in a relatively new but rapidly growing field of bicycle technology. The challenge they face is how to scale up their micro-manufacturing operation without losing the precision and quality that defines their approach to a universal problem.

VISIT: Atomic22, bicycle security specialists

VISIT: Atomic22 - Cycle Security Specialists

Call it the road less travelled; describe it like climbing a vertical cliff; measure the unlikeliness of it actually working: first, to design a security skewer that thieves can't foil, then extend it across the architecture of a bike to all the beautiful parts that can be taken at the twirl of an allen key. Finally, to commercialise the results but keep the manufacturing on site, in the UK, to standards that would be immediately apparent to the likes of Cliff Polton (founder of Royce) or to use a Stateside example, Chris King.
Patrick Wells and Ayantika Mitra started out on this gruelling path back in 2009. Four years later they have a small, CNC-equipped facility on a rather lovely business park situated amidst the flowing hills and woods around Horsham, West Sussex. Just as importantly, they have a growing business on the cusp of expansion.
CNC means 3D manufacturing, and the magic sauce of Atomic22, if you like, is its invention of a security skewer with a three dimensional key/bolt head, so that the unique pattern to which each component is cut is unique in more than one plane.
Everyone Patrick and Ayantika turned to said this was impossible, but being beautifully unreasonable people (try that book - The Power of Unreasonable People, by John Elkington and Pamela Hartigan - it's full of brilliant examples) they ignored the negativity and kept at their metier. I don't know exactly how they did it, and understandably they don't want the world to know every detail, but they have.
At this point they have already worked through multiple prototypes for a wide range of security parts, centred around wheel skewers for both road and track/fixie.

Shiny sun, red bricks, fields all around

I met Patrick and Ayantika at Bristol Bespoked (AKA The British Handbuilt Bike Show) in 2012, and have just visited them at their facility in Horsham, eighteen months later. They struck me as completely dedicated when I first met them, incredibly intelligent in several fields (they both have weapons grade backgrounds in mathematics, to give you a hint) - and it's fantastic to see them again on their home ground, with several bikes hanging from the ceiling, a little resident cat called Pebbles, and precision machinery behind closed doors, out to the back (I was offered a glimpse but don't count on it - they've been plagued with the wrong sort of well-wishers, call them 'well-phishers').


Patrick Wells, Ayantika Mitra. Founder-owners, Atomic22
More than anything -and this trip confirmed it- they've got that gleam in the eye that says they're going to succeed.

Patrick hates what he describes as the 'cycle of misery' which results from so much of the bike industry importing so much low quality stuff from Asia, where we all know that there are sweatshops and worse.

 He spends a long time showing me the inner workings of a beautiful bike bell patented by his great grandfather in the years following World War Two, and then I begin to realise that this flows in his blood: precision engineering
The 'Harmo' bell by Fearnought Ltd. Pebbles top right...
mixed up with perfectionism. The bell in question features a clockwork element, with a push mechanism. It works beautifully today.

Moving over to Atomic22 products, he shows me the latest iteration of a masterpiece, the Atomic22 wheel skewer.
Patrick explains how it features a butted profile to reduce weight - it's not just about security - and offers a floating head to alleviate alignment issues, serrations to prevent movement or rotation, and a tab called a dog, also to prevent wrench-induced twisting or chisel-induced shearing. Meanwhile the threads are both internally and externally rolled, making them extremely smooth. The central experience I relate this to is the day I bought my first pair of ZIPP 303s. I described the skewers as jewel-like, and you can say the same about these.

Thieves will move on to less challenging targets
So who's buying them? Having already had great coverage at the NAHBS (North American Handbuilt Bike Show), Atomic22 is taking orders from all the markets you'd expect: USA, Australia, UK and Europe, plus a long ragged tail of other countries.
The biggest frustration is the sheer number of standards prevailing in bikes now, which makes measuring bolts more complex than it used to be and is set to get worse with the plethora of bespoke bikes, plus large manufacturers striving to be 'different', often for the sake of it rather than any meaningful advance. But that's where Atomic22 will need to scale up and take a view on how exactly to proceed. For now, the core customer is high-end commute (geared and fixed) and roadies, which makes eminent sense given the current state of the MTB sector.

I ended my visit by ordering a set of bolts for my Enigma - wheel, seat post collar, saddle and stem. I'll re-blog the results when they are in hand.

RACE REPORT: Three Peaks Cyclo-Cross Race, 2013


Camping by the River Ribble in Martin Hanson's field
Three Peaks Cyclo-Cross Race, 2013

The Pub at the centre of all the action
Difficult to describe this race, because it is an oddity, both within the British scene and the international one. The entire context of the event is actually fell-running, the peculiar British texture of this mad sport best described in Richard Askwith's loving portrayal Feet in the Clouds. The current race was founded by John Rawnsley in 1962, and it was really a super-imposition of bikes atop a fell running race. Fifty years later, in 2012, Rawnsley retired from managing it. By then it had attracted international attention. The best feature about the event and it's history was published in issue 34 (2012) of Rouleur, page 146ff. It's a brilliant feature.
The Start: Straining at the leash - and not only this Hungarian Vizsla  

Rob Jebb leading on Pen-y-Gent (Credit: S.R. Hall)

Pen-y-Gent, which translates as 'winds'. And there are winds.
This year's event -depicted in a handful of photos here- represented a watershed in the history of the event, being the first run by a committee led by Mark Richmond. They did very well. It was also a watershed because the 51st edition of the race was won convincingly by Rob Jebb for his 10th victory, a simply incredible achievement.

I said in my previous blog post that I would briefly revisit my various decisions, strategic and technical, to see what worked and what didn't.

First of all, I was not 100% race fit having battled an unhappy left ham string since June - in fact throughout the four months of specific training for this event. I came 486th out of 544 starters, of which 40 retired. I had entered in a realistic but determined frame of mind: let's do this thing and learn about it. Then regroup for a possible return.

That's about right: I don't think any amount of forum chatting can really get you ready for this one. You need to do it respectfully the first time. This event stretches cycling beyond its normal parameters. It also takes you way out of the normal 'comfort zones' even of otherwise hard-core Cross racing. First there's the running/climbing aspect, obviously, but then there's the terrain, the gradients and the wind (the wind was diabolical despite the sunny conditions - and it made everything much harder). I spent a good portion of the event wondering whether you can 'enjoy' the Three Peaks: it is a very northern, very austere way of having fun, epitomised by an ethos that served up one 'feed station', a white plastic cup of water and nothing else. The subtext was abundantly clear. 'If you were a real man,' said in a thick Yorkshire accent, 'this is all you'd consume for the whole event.' No garish sports drinks, no ghastly Nestle sponsorships (whisper The Etape), no gels, nothing at all. I really thought that was brilliant. Fantastic. The Last Outpost against commercialisation (although it still costs £50 to enter).

Another thing: there were very few overweight competitors, and the fifty or so women competitors were all absolutely brilliant as far as I could tell. Many of them had fell running backgrounds because I snatched the odd conversation with one or two out on the course. On the male side, it was a bit like a National Cross Champs with a smattering of foreign entrants from Switzerland, Belgium (especially), Germany and the USA. I wonder what they made of it all. The quality of the overall field was very good indeed: it was not like a sportive. Every single entry is vetted by the committee, so there are no 'have a go Harries'. There was a palpable respect when you got to the top of the last peak, but in between the encouragement was of a disciplining type. 'C'mon, step it up lad, this is a bludy race.'

On the technical front here's what I found out. I think I made the absolute right decision to fit Panaracer Cinder X 700x35s. They weigh 350grams. This is a strong, MTB-heritage compound tyre with an aggressive block tread. At 90psi (which it is rated for) it rolls well enough on the road. I stand by what I said before about the Schwalbe Urban Cruisers. They are really sluggish and weigh too much at 600grams. Equally, I noted that lots of riders seemed to turn up on the same tyres (700x32, typically) that they'd use on a normal Cross race. This is an error. The average Cross tyre is not strong enough for this course. You need strength and volume of air and a high PSI rating. Clinchers beat tubs unless you are very brave, and happy to change one in the field. I was confident I wouldn't puncture and I didn't. Panaracer flataway kevlar stuff may have helped; in the end I had a disaster with the Joe's sealant and gave up. Not before it had gone everywhere. No comment.

Shoes: As predicted, it was a case of swings and roundabouts. I was way out on a limb deciding to wear Inov-8 Mudclaw 300 fell running shoes instead of clip in SPD MTB shoes. I was very content with this, and so it proved, partly: I had a ton more grip and felt much more confident every time we ran. What I didn't realise was that you need to mount/dismount/mount/dismount at the drop of a hat all the way round. A bit like the world champs in the sand dunes. This is not so easy with clips and straps and fell running shoes with rubber studded soles. I had practised, but on difficult terrain I undoubtedly lost time reachiong down to lift the clip and get the shoe in. The overall distance of 61kms was as far as I would want to ride in running shoes. If I could find the right, 'flexi' pair of MTB shoes I might try that next time. If it was very wet you might still want the Mudclaws. There were lots of sections where this year's dry conditions made the paths dusty/slippery and people in stiff MTB shoes were just struggling to get any grip at all. That's a big risk of injury; ditto the wet grass ascent of Ingleborough, the famous 'cliff' that always gets photographed each year, and often where the initial selection is made.

Tyres and shoes are the two most important decisions you'll make. The other one is gearing and I was right about that too, based on advice from Konrad Manning, something of a veteran of the event. You want 1:1 gearing so you can ride much of the initial path up Pen-y-Gent, the last climb. On 34x32 (my set-up), it's marginal. You are so wasted by then, you can only ride small sections and then have to dismount and walk/run. It would be much better to have 32x34. This is crazy stuff outside of the context of this event and takes you off into special kit and expensive prep. But that is what you would ideally have. I didn't have it, but then lots of riders had turned up with 46x36 / 12-25. Stock stuff for school playing field racing. I hope they enjoyed their running legs.

Summary
It would be strange to talk of enjoying this event. The technical demands are so steep that you cannot enjoy any descent as such; I crashed three times to prove that point, once heavily on the descent of Ingleborough. But it is mentally engrossing and by the end you are completely drained. I'd compare it to a bad weather fishing trip that yields little, but the little brown trout you finally catch using a pure method, say dry fly, is worth the wait. Or, a gold panning expedition where you have to pan for hours with nothing, but finally reveal a single, perfectly formed nugget of gold. This is not like an Etape where you get to play the Pro on a 20km descent at wild speeds, pure good fun. It's much harder and drier than that. But, you do have your wild off-road moments, or other moments of beauty; it is very authentic and there are no losers in this event. At the end of it all you're supposed to have a laugh and drink a pint, exactly as the fell runners do. And by then you know that you've done something much, much harder than the Arenberg Trench of Paris-Roubaix fame - which pales in comparison.

REVIEW: Schwalbe Ultremo DD Evolution tyre

The Schwalbe Double Defense -good but it has limits
REVIEW: Schwalbe Ultremo DD Evolution 700x25c tyres £35.19 (Wiggle)

This is not the tyre that most often crops up in the Schwalbe range - it's usually the Ultremo ZX, a pure road comp tyre, or the very popular Durano and friends.

I picked out the 700x25c for its relative light weight (260g) and widely touted puncture resistance (see below the many claims) - as a fast but commuter-savvy tyre capable of handling a rack and panniers laden up to about 10kgs in a commuting only situation. Fitted to my new Enigma Ethos on black Mavic Aksiums, they looked the part but I was always worried that the tyre was too light. For the spring and summer months I never had a problem, but when the rains came two weeks ago, I began to fear the worst - it just feels like a race tyre being stretched to capacity than operating well within its strengths.

Here's the highly persuasive marketing blurb from Schwalbe:

"Cuts by glass shards, or sharp flints are effectively repelled. Weight and rolling resistance remain low. Naturally with Triple Nano Compound. HD Ceramic Guard - This unique, high density fabric offers highly effective protection against penetration punctures. The additional coating of tiny ceramic particles blunts small shards of embedded glass, so that migration through the tyre is stalled. SnakeSkin. The addition of "snakeskin" protects the tyre shoulder and side wall against sharp rocks and broken glass. Although side wall defects are quite rare in road racing, it is still annoying when it happens. And worse, the tyre is often not just punctured by a cut, it is frequently completely destroyed. Double defense is the best prevention against this happening."
Here are the limits - don't know what caused this hole

Part of a winter, Paris-Roubaix and Tour of Flanders - now for commute
Well I'm sorry to say this but my back tyre ruptured big time the other day, riding across London in the wet. I never got to see what I hit but it was probably a shard of bottle glass. The cut, pictured, went right through the tyre and I had no shoulder with me so rode home on 50 psi, gingerly, thinking that any more pressure would likely force the tube out through the hole and leave me stranded.

My immediate thought was that this is a summer tyre or maybe a three season training tyre, but it's not really strong enough for commuting.

Turning to the winter then, I considered buying new Duranos, or even Pluses, or maybe a combo (Durano Plus at the rear, Durano at the front). But I had these last winter and I know they're great. The point here is to try something new.

So I dug out the Vittoria Open Paves that have already seen serious cobble action, and am going to fit the pair with Panaracer Flataway between tyre and tube, a sort of kevlar fuzzy band with adhesive. Make no mistake this is a totally different philosophy of puncture prevention, before we even get to the Panaracer stuff: the Open Paves reply on density (320 TPI =threads per square inch), and a kevlar component, and also a profile where there is more meat in the actual tread than the walls, more so than competitior tyres. Plus, they're 700x24c - an unusual size - and I have always liked their feeling of just being that bit stronger. I'll report back come the Spring. If I have to estimate the weakness, it will be from cuts that just slice the rubber irrespective of the TPI. But if so, it won't be any worse than the piece of glass that just went straight through Schwalbe's HD Ceramic Guard.
