Compass Bon Jon Pass Extralight Tyre Review

April 8, 2016

I don’t often write reviews. Choice of equipment is very personal: experiences of the same component or item of clothing are subjectively variable and I have bought many disappointing items that others love. That doesn’t mean they were wrong, just that I don’t see the world their way. I will however tell you what I think about Compass tyres (tires in US), or more precisely their 700 × 35c Extralight clincher, the Bon Jon Pass.

Compass tyres are widely promoted in the randonneuring world having been developed by Jan Heine with Panaracer in Japan. They are reputed to be light and supple, are good at low pressures and come in a wide range of sizes (up to 38 mm for 700c; wider for 650b and 26″). They are indeed objectively light and supple, and are available in a very pale skinwall version, or all black.

I chose the Extralight version as I am a puny lightweight and thought I could get away with it. The Bon Jon runs tubeless, but I’m running them with standard butyl tubes because I am a late adopter. They fitted quite tight on the stock rims on my Whyte Suffolk (made by Alex I think) and took a while to seat properly – I inflated to about 80 psi to make sure they were seated and have settled on 40 front and about 50 rear (I weigh 58 kg): I could probably go lower but I think I will wait until I go tubeless sometime in 2020. My first ride was at 60 and 55 which seemed a little high: at the lower pressure I can descend very quickly and confidently although if I climb out of the saddle the front tyre looks absurdly squishy.

So, apart from excellent descending in all weather, how do they ride? The only time I have regretted being on them in their first 750 km or so was lost on a farm track where the road turned to mud and was upward. Tarmac, cobbles, gravel (big and small) all seem fine. Even a bit of mud is OK if one is not trying to climb or get started! I have done two long rides on very mixed terrain and they were comfortable and felt very safe (and I am awful off road). The lack of side-knobs or raised tread would only bother me in really muddy conditions. On the road they are luxurious and I don’t think they slow me down.
The main reason I chose the 35c version was frame clearances. They fit my frame with just enough room (the chain stay clearances are unnecessarily tight) for safety, and I can just fit mudguards to keep ride companions happy. No punctures yet and I have removed one sharp flint from the tread; the flimsy sidewalls still seem fine after some rocky path encounters.

For mixed riding and/or long distances they are quite the best tyres I have ridden. I intend to use them on my next 300 with George and Gavin in May and I’ll report back after that, but after 105 km of awful cycle path, track and chipseal roads yesterday which delivered great comfort I am not expecting to be disappointed.

You can buy Compass tyres direct from Compass themselves (see Jan’s original blog post about the newer tyres here) or if you are in the UK you can get them Extraquick and Extralight from Velo Vitality in Brighton. They aren’t cheap, but good tyres never are… in my opinion!

NB I paid for these tyres myself and have no connection with Compass or Velo Vitality other than as a happy customer.

The map is not the territory…

April 6, 2016


I wonder what this will actually feel like? RWGPS makes route planning seem easy, but there is a surprise on every ride. After the familiar sections of Yorkshire are accounted for this route contains just enough mystery to imply a test for more than my legs. Between GPS and reality exists a fruitful gap which should get me into plenty of trouble. I could just get the train both ways and take my Brompton but I have convinced myself I am short of kilometers, and the allure of unfamiliar territory and a necessary change from my normal commute is just too tempting. In particular, I confess to never having ridden the Aire Valley Cycle Route , and my experience of off-road cycle provision in the UK is rather mixed but generally leads to something “special”. I also have some serious thinking to do about work and here is a chance to let my unconscious do the work.

Here’s to getting lost!

(BTW I am not really going down a section of the A1…)

Third time lucky?

February 22, 2016


I completed my third North-West Passage on Saturday. It doesn’t sound much put like that. Despite a comedy of errors which included forgetting my bottles and phone (only one of which I went back for), I completed it. Moreover, I managed not to get lost on the final run into Rochdale. However, due to the worst wind and rain I have ever endured on a 200, I can confidently claim this was the hardest ride I have finished. So hard that the best bit was the (dry) A6 through and South of Lancaster.

Sometimes arriving is all that is important and a ride is somehow incidental. It is never quite like that because the experience of arriving at a pub you left earlier isn’t the same when the intervening twelve or so hours were like being punched in a cold shower by an Irish classics specialist. But yes, on Saturday I was just content to finish. And then back out shivering into the night for the hour and a quarter home…

The Ghost in the Machine: underneath the tinfoil hat.

February 2, 2016

I have been struggling for a while to decide how to continue to write about cheating in sport given its state of anomie. Scandal after scandal in athletics, soccer, tennis (and even cycling) have helped normalise the view that sport is actually inherently fraudulent, whether or not that is in any sense ‘true’. Nonetheless, two developments in sporting fraud have emerged which suggest a post-humanisation of sporting fraud. Neither are entirely new in concept, but both engage with human performance in ways which question the boundary between technology and the body, and create a gap between our inquisitive nature and what we can comprehend as either human- or machine-like.

  1. Gene Doping
    The ability of products to manipulate the inner workings of our cells isn’t all that new, and many journalists have latched onto the warnings about dangers (turning something on doesn’t mean you can then turn it off) or the potential for such products to be both potentially undetectable and incredibly powerful. One such product which has never exited testing or been brought to market is Repoxygen, which causes an alteration to cells which then produce higher than normal levels of EPO. Whether this exists as a black market product is unclear but it is certain that athletes, coaches and sporting authorities believe that to be likely. The crucial difference between Repoxygen (or a similar product) and rEPO is that whereas doping with rEPO decreases the production of EPO by our bodies whilst boosting red blood cell production, Repoxygen acts directly on the cells increasing their production of natural EPO. The trick is to do so without creating chronically and dangerously high hematocrit levels. That does not happen with rEPO – which suppresses natural production of EPO and is therefore relatively short lived in effect.
  2. Technological Fraud
    The second development, which although highlighted by recent events at the U23 Cyclocross World Championship event, has been posited for much longer, is the use of small concealed electric motors to boost cycling performance by a marginal, but significant quantum. There is a suspicion amongst some that Femke Van den Driessche used such means to achieve her gains on the climbs at the 2015 Koppenbergcross – a suspicion that may have helped motivate what looked to be a targeted operation to detect the motor using an EMR application in the pits at the World Championships.

What links these two techniques is their invisible testing of our assumptions about what it us to be human. Of course, all cycling is technologically enhanced, but whereas an illegally light bicycle is only quantitatively illicit, the motorised bicycle is qualitatively illicit. We assume the power input which the drive train converts comes from the rider and if this is no longer the case we are watching a motorcycle race, not a bicycle race. With gene doping it is not the undetectability or effectiveness which chills, it is the categorical shift from human to… not human. In both cases there is an uncanny valley effect where in the absence of better preparation, whether natural or pharmaceutical, the athlete goes beyond what is possible for their physiology. The results of doping can look odd to the naked eye, but the result of gene doping or technological fraud create a categorical shift. This is no longer enhancement by degree, but a new sport which goes well beyond the metaphorical Lance-as-cyborg narrative.

Human beings are fairly inquisitive: I’d guess around .7 on the cat scale. Their desire to gather and interpret data is not always matched, however, with the intellectual capacity to come to conclusions that bear much relation to reality. Whether it is rappers thinking the Earth is flat, or the mistaken belief that there is a causal link between autism and the MMR vaccine, our desire to explain what we observe can outstrip our ability to interpret. Of course, it’s worse than this: the desire for an explanation may not drive us to seek information upon which to ponder; and it can be manipulated by the unscrupulous. It may drive us to select information which reinforces our existing beliefs; or to reject information gathering and rely upon solipsistic deduction of a kind Sherlock Holmes would be distinctly uncomfortable with. And sometimes, the explanation is so seemingly crazy it can lead to madness…

The detective novel plays with this desire for explanations, and also the pleasure we gain from being just one step ahead of the detective (or one step behind). And although we often look to be searching for the smoking gun, its discovery often disappoints as well as befuddles. The reveal undoes the setting up if explanations, unless through shock (Seven) or unexpected confusion (Usual Suspects) it itself sets up a new set of questions. It takes a deft artist to tell a tale which simultaneously unfolds into a rational state of closure yet still leaves us questioning: perhaps this is why the confusing “reality” of time travel narratives, whether hysterical (Interstellar) or creepily whole (Predestination) are so fascinating.

So where does this leave the inquisitive cycling fan? All sports fans have some degree of fascination with the causes that sit behind winning. However, many of these factors are hidden, either because they are forbidden by law or rule, or because they are too complex for any but an expert to really grasp. These ghosts in the machine of sporting excellence lead many of us to express our inquisitive nature in fantastic, ill-evidenced speculations worthy of the X-Files. The truth is indeed out there, however, and it isn’t our fault that the UCI have to use ghost detectors to combat technological fraud. Who can blame us for retaining our tin foil hats when if turns out that a form of cheating much derided as fantasy turns out to be both actual and invisible, yet needs only the right tool (a free EMR detector app) and a tip-off to find.

Sunk costs and the long distance cyclist

July 24, 2015

20150718_145414Cycling’s most potent mythology is best signified by the death of Tom Simpson: continuation past the point where the returns diminish to zero or less is admired by many even where it is frankly pathological. In order to meet the demands of this myth, it is no surprise that some resort to doping, or make other physically or mentally disastrous decisions. As riders prepare hopefully for Paris Brest Paris, the Race Across America or the Transcontinental (starting tonight in Belgium) they probably hope that they will not have to go beyond the bounds of rationality to finish, but by the very nature of even the shortest of these challenges (no longer a race) demands a suspension of belief even for repeat entrant. The exposure of the body to such sustained repetitive action is unpredictable but always extreme, and even the least imaginative of riders will know that they will have to proceed beyond any normal definitions of plausibility. Such prospective irrationality only gets worse as a rider accumulates time and distance leading to bizarre and sometimes catastrophic failures which could be minimised by stopping hours or days earlier. However, it is almost impossible to judge whether continuing is rational or not: when even starting goes against common sense, how can one decide when to stop? Riders’ accounts demonstrate that successful completion can come despite all the signals to stop, and for supported rides the rider’s team are often better judges, making their decisions based upon more rational bases. Even support teams, however, can suffer from the sunk loss fallacy. If continuing past an obstacle brings failure there is no advantage in continuing, yet riders continue until they fall asleep whilst riding (and crash), ignore injuries that will eventually lead to abandoning, or carry on rising despite the unlikely average speed required to meet a time limit. As the distance increases so does the investment, and the magnitude of the potential loss. Of course, the paradox is that it is incredibly hard to tell where the threshold between a reasonable decision to continue and abandonment lies. Viewed from outside the world of the long distance racer Josh Ibbet’s decision-making on the way to his second place in last year’s Transcontinental looks foolhardy. Judged purely on outcome, however, his decision to ride through pain and exhaustion was successful (if costly). If such decisions were made on irrational grounds, and merely to avoid discarding sunk costs, that hardly matters unless you permanently injure yourself… as long as you make your goals. As an aside, the result of abandoning the investment one has made can be a transfer of that energy into surprising alternate goals. Martin Cox’s extraordinary decisions to transfer his energies from racing to cleaning up the Stelvio and helping out an injured companion of the road are examples of constructive ways of dealing with what might otherwise look like losses.

What does any of this have to do with me? I sank time, money, effort and spirit into my attempt to ride Paris Brest Paris this year. I prepared well, and pre-qualified last year to get an early entry by completing my first Super Randonneur series in 2014. And yet I gave up on my final qualifying ride of 2015, unlike @fabiorandonneur, who endured many challenges and qualified last minute by completing a 400 under extremely painful circumstances. I overslept in the night after a very bad run from Castleford to Mytholmroyd and completely lost my will to continue. Although officially out of time I could have tried to continue with the hope of catching up on the rather flatter final 225 km of the East and West Coasts 600, but after about 10 km of grovelling into a headwind I returned home and slept for about 18 hours on and off. It wasn’t supposed to end this way, but after20150720_113944 tears came resignation and the memory of an enjoyable first section before I collapsed in the night.

The story didn’t end there, however. Unlike Martin Cox I didn’t manage to sublimate my drive into anything selfless. I did, however, complete a similar route last weekend in 37 hours (validated by GPS), an hour quicker than last year, to complete my SR series for 2015. It was alone, unsupported and beautiful, leading to no glory in Paris, but the return on my investments was just right, thank you, including fish and chips at 500 km.

Feeling the pressure

June 11, 2015

I tend to avoid fixed, singular goals. I spread risk to mitigate disappointment. A lot of academics find solace in the short term shifting of attention from one priority to another, and become frustrated when they are managed too directly or become unable to do this due to sheer volume of work. Last year I committed to completing a Super Randonneur series – and when I failed to start my 300 I filled the gap with a late-season DIY by GPS ride. This season has thus far proceeded in a more orderly fashion, pointing threateningly but inexorably at the start (or end) of Paris Brest Paris in August. Although each ride on the way is an achievement in itself there is a tendency to subordinate these successes to the larger and more singular goal. Anything apart from success starts to look like failure.

640px-No-DozUnderstanding cheating on a personal, rather than an academic level, requires immersion in the high stakes of goal oriented behaviour: cheats become blinded to the larger consequences of their actions because their focus on outcome and often seem surprised by the impact of their dishonesty on others. For them, doping is a personal thing: for others it is an attack on the order of things, calling into question the assumed truths of competition. So, am I becoming susceptible to the temptations of assuring myself through the abuse of medication? And would it matter? On my last qualifier I took a few caffeine gels with me and attempted to deploy them in my battle with my prior lack of sleep. In retrospect I should simply have prioritised my sleep before the event but I have a busy job and family life – it’s easier to pack a few gels than manage my sleep. Of course, there are in fact no anti-doping regulations for PBP (EDIT – see John’s comment below, I am mistaken) AND no testing (although doping is illegal in France) but for me caffeine gels crossed a line (over which are caffeine tablets and then almost anything goes…) regardless of any written rules or laws (I have written elsewhere about doping and medication in randonneur events). I should have taken my own advice from last year:

I finished my first 600km Brevet on two cups of sugary tea (the only caffeine I ingested), water, caffeine-free sports drinks, gels and energy bars; I may have had a can of coke, but I’m pretty sure I didn’t. Real food: cheese sandwiches, fish and chips with mushy peas, flavoured milk… and a vegetable samosa. After the ride, I took some ibuprofen to calm the inflammation affecting my shoulders and hands, but not for long, because it makes me feel vile. I am still in pain four days after finishing, and suffering from altered sensation in both hands, although I am now much improved. It may be that my approach is unnecessarily puritan, or not puritan enough (get rid of the space food) but it wasn’t really considered: like the lovely guy riding a Pashley roadster I just did my own thing. You may choose a different path…

More importantly, my recent experience of sleeplessness has led me to question what I am willing to sacrifice. On the Monday morning after my 600 at 0900 I will be serving on a disciplinary panel – I’m not willing to let this affect my ride but that’s going to be a challenge. I start PBP (if I qualify) straight after a torrid week at work but that’s not yet led me to back out. I am proud of my new ability to avoid self-sabotage but there’s some danger of heading the other way and risking my health or safety (or my competence as parent or manager) by being too goal-focused. I will try to employ common sense and prepare to work around adversity, but as I noticed in my last qualifier the lack of stress can be a factor in my performance – I need a fair amount to be optimally aroused and alert and a few disasters on a ride seem to perk me up. With that in mind, my 600 is on the very last weekend for PBP qualification. No second attempts. I could really do with a load of support to ensure I get round, and if I fail, to deal with my disappointment. Fortunately I have that at home but every extra bit helps.

And I may not even like it if I qualify….

Here’s the link to the AUK calendar page for the East and West Coasts BRM600 which I will be riding on the 20th and 21st of June.

Sleepless in Goole

May 29, 2015

The Marie Celeste at Leven: still light but getting late.

I never thought I had a problem with sleep – or should I say its lack. I’ve ridden a fair few overnight rides, and spent about 6 years chronically sleep deprived as a parent. On 400 km audaxes I often feel a little sleepy around dawn, and I managed my first 600 on just one hour. I had planned for about 2-3 hours on that one, and although I became a little anxious when my plans unravelled I felt pretty awake for most of the ride (despite audax fury trying to find a working cashpoint as proof of passage in the night).
