Quest for Tyres (& forks!)







Sourcing commuter/everyday tyres for a group test feels reminiscent of the Commodore 64 classic about a uni-cycling caveman called BC, who weaved around prehistoric, pixelated canyons amassing replacement rubber. 

Just as grass roots racing still stars bikes brewed using an eclectic mix of reciprocal parts hung on older, though worthy framesets; there are no hard n’ fast rules.  Some folks with mechanically sensitive riding styles prioritise minimal rolling resistance and are willing to accept greater vulnerability to sharps, holes and other nasties.

Others prefer the belt n’ braces combination of a really tough 30tpi casing, aramid belts, thorn repelling inner tubes and a slightly stodgier ride.

One thing everyday rubber needs to be, is dependable otherwise you won’t fancy riding. No matter how proficient or prepared you are, there’s nothing pleasant about roadside tube swaps and patching damaged casings fifteen miles from home when its pitch black and minus 5! 

Vittoria have always enjoyed a strong following and their UK importer has kindly sent me their 26x1.6 street runner and 120tpi 700x35c Voyager hyper. The street runner is basically a fast rolling urban mtb semi slick, whereas the voyager is marketed as an “Ultra-light touring tire has most of Pro Series race technology. Grip, comfort, handling, reliability, good look: this tire has it all!

Hmm, proof of the puncture resistance and overall performance lies in daily service but both seem pretty keen so far. Also begs the question of where my workshop tyre wand has vanished to...

Irrespective of product, someone will always find limitations (as distinct from fault). Some people are just genuinely harder on equipment than others. Back in the late 1990s, I regularly attended the Brixton Cycles “Beastway” mountain bike racing series held at London’s Temple Mills Lane and recall one rider saying he’d destroyed countless pairs of high-end cross country race wheels.

There wasn’t any obvious explanation-yes; he had an aggressive technique, though hardly abusive. Then, during the course of conversation, it transpired he exceeded 90 kilos-markedly heavier than might be expected of a man standing 175cm (5’9) tall.

Staying with surprises, those 32mm Kenda Kwicker Bitumen have proved their worth these past fourteen months, only puncturing once in 5,000 miles-easily remedied with a sturdier tube, suggesting the Iron cap technology is genuinely effective.

Lacking the outright invulnerability of their Iron Cloak (Aramid) series, or indeed Schwalbe’s slightly portly “smart guard” system (that actually deflects sharps rather than drawing them inboard) Iron cap denotes comprehensive puncture preventative strip spanning bead to bead but with vastly superior wet weather manners compared with some similarly priced rivals.  

Rolling resistance isn’t bad for a 60tpi casing either (when run at their 85psi maximum) either. Sure, the tread is beginning to sport some obvious signs of wear along the centre-strip but I reckon we’ll reach 8,000 before retirement beckons. Popular lore advocated alternating front and rear tyres for uniform wear/optimal economy. Indeed, it was an enticing argument since, depending on rider/braking technique, the rear can be exhausted almost three times as quickly.

Alas, just as fork, rather than frame failure is most likely to result in serious injury, the same goes for a front blow-out. Thrifty folks, desperate to get their money’s worth and who employ similar pairings can extend their lifespan by replacing a worn rear with their existing front and letting the factory-fresh unit lead. Exhausted tyres are best reincarnated as belts or “boots” (cannibalised strips used to bandage and reinforce nasty lesions in otherwise healthy casings).

Two suitable disc specific fork candidates with mudguard eyelets (for the Ilpompino’s front end transformation) have arrived at once. Imports intrigue me but I’d sooner do business with a domestic supplier. Ticket prices may be higher, though faults/warrantee matters are straightforwardly addressed and there’s no nasty import tax hangovers further along the line. Making do and retrofitting to the fixers ITM Visa blades seemed another tangible option. In reality, the band-on breed seems decidedly low-rent.   

Contrary to my earlier remarks about TRP’s HYRD being too prestigious for said build, the lure and practicality of a self-adjusting open system seems way too enticing and for me at least, justifies the additional cost over a mechanical calliper. Donning bandanna, huge hoop ear-ring and gazing into my crystal ball, I see a machine built front 32hole hoop, laced two cross to Shimano’s venerable M525 (Deore) cup n’ cone hub…

Deore, rather like its STXrc predecessor is a very serviceable, inexpensive groupset that delivers plenty of smiles per mile but doesn’t dictate re-mortgaging should something break. Cup n’ cone hubs have been superseded by sealed cartridge types but are mechanically simple and very smooth when striped and fed decent quality waterproof grease at regular intervals.    

Aside from some intensive brand management/promotion of “Seven Day Cyclist”; I’ve been introduced to an artist who might be willing to bring “Claud the Butler & Friends” to life on a royalties basis. There’s been renewed interest from publishers too; although the whisper of self-publishing has intensified into a gentle roar.

Arguably an internet phenomenon but we’ve all become very comfortable with the notion of free goods/services. I am a firm believer that people’s time and skill need recognition and should be remunerated, or at least repaid in kind.

Laid Up with a Lurgi ?










Just crossed the three hundred mile marker on the Croix de fer 2.0 when Joshua’s viral infection decided I was its next host. While a less catastrophic assimilation than those depicted in John Carpenter’s seminal 1982 shocker “The Thing”; nonetheless I spent two days and a further three nights in a feverish and convincingly comatose state, moving only to expel gallons of phlegm into the dog’s previously empty water bowl…

Reverting to more appetising propositions, these past few weeks with the Genesis have awakened a strange and irrational yearning to equipping the Ilpompino with a disc-braked front end. 

By my own admission, such urges belong firmly buried in the “want” vault since we’re talking new fork, wheel build, calliper, cables and related disc components. Then of course, a single, well-honed cantilever is more than adequate for stopping a speeding fixer and 70odd kilo pilot.

We’ll blame it on the fever for a moment since these usually induce a strange, contemplative state of euphoria somewhere in their gestation. Is Northern Soul simply an excuse for wearing big trousers and recreational use of amphetamines? Why does the scriptwriting process for certain “flagship” TV soaps apparently employ so little hard research? Has mainstream politics lost its legitimacy?

Joking aside, those TRP HYRD fitted to the Croix de fer, were the real catalysts for this proposed upgrade. For the uninitiated, they’re a hybrid design employing an open hydraulic calliper-with all the obvious benefits yet commanded by a high quality cable, thus maintenance/repair are pretty straightforward and they’re fully compatible with standard road/brifters.

Costs for this sort of specification aren’t outlandish by any stretch of the imagination but too exotic for said fixie. A quick wander round the web suggests something Deore flavoured with corresponding front hub and a shop branded carbon composite fork/aluminium alloy steerer is a more cost effective and therefore, realistic proposition. Not a priority, rather one to seize should a suitable ensemble come under my radar and moreover, at the right price.

Maybe it’s just another illustration of the “Confirmation bias” in full flow-the notion that “When men wish to construct or support a theory, how they torture facts into their service! (Mackay, 1852/ 1932, p. 552)” However, further trials of driver-less vehicles add fuel to my particular belief that Public Service Vehicles (Buses, Trams etc) along with Heavy Goods Vehicles will become fully automated within ten years.

This has a wealth of implications and contrary to widely held opinion; technology and development is not neutral. It does not exist in a separate sphere but driven by the inventors’ (or corporations) own ideological leanings.

At the moment there are questions of their hazard perception programming/equipment. How will they recognise, or indeed distinguish between cyclists, motorcyclists, horse-riders, pedestrians, children/adults etc? 

When will these calculate is the optimal point/distance for overtaking? Human error is to blame for a great many accidents but at some level, computers are still potentially flawed in exactly the same fashion as they’re programmed and developed by humans.

Because the technology has come on stream, does this mean it will flourish by default? Does it actually toll the bell for commercial drivers as I first thought, or is it a proactive response to a dying trade, aging operatives not being superseded by young blood?

Computers are excellent at fast paced calculations and repetitive tasks but while they can operate within pre-set tolerances, they still cannot determine whether something is correct beyond this coded framework.

I can see the possibility of android operatives, housekeepers, companions and pets a’la Ridley Scott’s Blade Runner, though feel humans will not be replaced, or made redundant in the flavour suggested by proponents of de-skilling theory. Public perceptions of photography fuelled by falling prices and point n’ shoot technology implies there is no longer any mastery required…  

Another thing that’s been with us since time in memorial and similarly variable in quality is the humble paint defending patch-kits. You know the sort; they stop cable outers chewing through your head, seat tube but were notorious for peeling come the first hint of a muddy trail, sudsy bucket or lick of solvent. 

Technology filtering through from other industries (“Helicopter tape” being the most obvious example) has forced manufacturers to develop vastly superior versions.

Zefal skin armour large shown here is a comprehensive ready cut set made from 250 microns thick polyurethane, which is supple and extremely stretchy at moderate temperatures. Good, unhurried preparation is pivotal but proved delightful to fit and hasn’t shown any obvious signs of cultivating that fuzzy, filmy outline to date.
