Deviating from the Script Once More

Michael, Michael quite contrary tell me how does your fleet grow? Why, with Miche Primato dual pivot callipers, one inch carbon forks and band on bottle bosses all in a row...
Predictably there's been an about-turn on the Teenage Dream's fork choice-the chrome plated 531 blades complete with threaded steerer were a lovely idea until the "Out of stock" reality hit home. Mercifully Acor's UK distributor, Greyville enterprises have been kind enough to oblige with a carbon unit identical to those sported by Ninja Blue. Alas, the courier, despite having clearly read my note detailing a safe place to leave said forks returned them to the depot!
Impulsively, I've upgraded the budget "performance" calliper in favour of this higher end, Primato sibling-shallower drop, stainless fittings and less generic pads has transformed stopping prowess, modulation and feel. Overkill, given the braking requirements of a minimalist fixed perhaps but far from languishing in the spares drawer, the Performance, with 57mm drop and upgraded pads have sufficient fender clearance without looking "gappy" so will serve the Teenage Dream admirably. Funding these upgrades was the sale last weekend of my unused BOB YAK.

Selling stuff can demand both stoicism and resolve. There were hoards of enquiries from people curious about the Yak-in other words, cyber chancers looking for stuff to sell on eBay. They're quite easy to spot and often seem confounded when you politely decline their offer. One such individual-smacking of a dealer posing as a private consumer; demanded to know what I'd do in the event of not finding a buyer. My response advising I "would simply keep it" clearly left him dumbfounded! My reasons for selling were two-fold, this shop branded copy had come my way and there's no sense in hoarding duplicate stuff that isn't going to be used. After this tide of time wasters, a genuine buyer drifted in, questions were asked, photos exchanged and the deal done. My healthy, robust sense of cynicism suggests the Beast of Burden has a good home and won't find itself on eBay. I'd sooner pass kit on for slightly less to someone who'll enjoy and get use from it.As these photos illustrate, the other distinct advantage of the shop branded copy is its ability to fold compactly inside the waterproof tote bag for easy storage!
Now, these funny little bits of nylon might excite those of you seeking to carry bottles on frames sans braze-ons. True, bosses are easily added to steel frames but you'll scorch the livery-not an issue timed to coincide with a re-spray but some folk like to retain a frameset's originality-especially a classic. Adding braze-ons can also weaken structural integrity-not alarmingly so but some tubesets are more sensitive than others. On the subject of frame properties and specifically issues of rigidity and strength etc, wandering around the web,I happened upon this very interesting study suggesting that good old 531 (now in it's 73rd year) holds up remarkably well against wonder materials in controlled testing.

http://materials.open.ac.uk/bikeframes/bikeframe.htm

Pop-riveting bosses to an aluminium frame can induce similar feelings of revulsion and under the saddle/seatpost mounts aren't everyone's bag. These clever and aptly named "gizmos" can be positioned on the down or seat tubes and accommodates most standard cages without difficulty-just make sure you measure the tube diameter so as to get the right size-padding them out using shims fashioned from defunct inner tube looks second rate at best. For the time being, I'll stick with the Bor Yeuh bottle caddy but these plastic ties were worth experimenting with.

Belt transmissions remained a quiet force at Eurobike and while dividing many of us into simple love/hate dichotomies, Fixie Inc seem very committed having devised the Klick-Flip-the worlds first flip/flop hub for belt drives. Using a six bolt locking system closely resembling a mountain bike disc hub ensures precise alignment-there's no discretion with a belt as anything less than perfect chain line means both uneven wear an reduced efficiency. Supporters of this system cite greatly improved acceleration and transmission braking, zero lubrication and weight savings of around 300g over a comparable chain drive. keeping an open mind, there's still a sense of de-ja vu sweeping over me . Belt drives have been tried before and while undeniably quiet and mess free, debate rages over efficiency, durability and cost of replacement.

Snow drags back the foot that's slow... The dogs of doom are howling low...Well, we've not reached that season just yet. However, I'll take the opportunity to give frames and newly resurrected trailer a booster application of Waxoyling. Given last week's concerns surrounding the chemical composition of some workshop staples, it seems ironic and possibly hypercritical that I have ploughed surplus proceeds from the trailer sale into acquiring a batch of biodegradable miracle cleaners, degreasers and sufficient car wash/wax concentrate to set myself up commercially. Rest assured, corresponding quantities of Latex examination gloves were not forgotten.

Cranking it Up

Lo and behold, days after my last entry, this substantial hot forged Stronglight track crankset came under my radar. Adding 220g to the build might fill some with horror but in practice, power transfer is greatly improved thanks to the rigidity of the arms. Coupled with a deep section CNC machined chainring, this largely addresses the shortcomings of square taper designs whether climbing out of the saddle or full out on the flat-at least for riders hovering between 70 and 80 kilos.

Dual sided SPD make a great deal of sense on a road fixers but then these Look KEO copies sport magnesium bodies, sealed cartridge bearings and tip the scales at a very reasonable 220g (pair) while giving an aesthetically sharper feel. Magnesium has been criticised for being whippy but charging along the climbs, out of the saddle with my full weight atop them, I haven't noticed any of the dreaded flex and engagement's only fractionally slower when snatching away from the lights.
With the nights drawing in, the murkier and dare I say, grimier season looms large on the horizon. Less daylight demands better time management and my attention turns to convenience cleaning products-bike wash, hand cleansers etc. Being honest, save for working bikes serving in crime ridden, inner city districts, the promise of effortlessly gleaming steeds in minutes is a real crowd pleaser but in keeping with some washing detergents, ingredients can be a real witches brew.
Anyone involved in the repair side of the auto industry should be only too aware of the dangers associated with prolonged exposure to petro-chemicals and their health effects. Probe deeper into these wonder potions and often you'll discover hormones and carcinogens closely associated with infertility/birth defects, cancers and other physiological change.It's nothing new or restricted to industrial applications-these are commonly found preserves and stabilisers in cosmetics/toiletries.

Large manufacturers promote their benefits for the lowest possible price and as consumers we passively collude without thought to the longer term consequences. Equally, those boasting super invasive, filth busting formulas must also have some degenerative effect upon welcome lubrication. I for one am careful to avoid spraying such formulas-even citrus based, directly at headsets, hubs, bottom brackets. Fussy? maybe but there's insufficient evidence to suggest these chemicals, ingested through the skin don't mutate or contribute to disease or illness. I'm not trying to cultivate paranoia but it's food for thought and gloves, Latex or otherwise are wise precautions when working with them.
Nothing gladdens the callous hearts of bike-thieves more than a nice, shiny anonymous looking bike they can flog quickly without trace. Therefore, I've opted to treat Ninja Blue and the Teenage Dream to Alpha dot. It's been on the market for a good decade or so and feedback suggests it's like kryptonite to the professionally light fingered and insurers lower their premiums accordingly. Like any other tagging system, there's no substitute for solid, properly used locks and secure storage but they mean bike and rightful owner stand a hope of being reunited. It's a lacquer containing a unique code linking bike and owner courtesy of a central database. Unlike transponder systems which are easier to dispose of, a thief can never be sure they're removed all trace and can be applied to most surfaces without affecting paint, lacquer, plating or anodizing.Last but not least, the Univega finds itself sporting this nifty T section alloy cage designed to haul 1.5 litre PET bottles without flinching, making those impulsive roadside purchases easier to cart about. Measuring 33cm long, fitting's tricky on compact framesets, demanding I forgo one mounted on the seattube but the benefits outweigh the shortcomings. That said, I've a feeling my dentist doesn't share my enthusiasm!

Pedalling Contradictions

Some rides flow seamlessly while others have very clearly defined beginnings, middles and ends-Sunday's mid morning meander being a case in point. With the strong autumn sun calling it was time for Ninja Blue and I to take advantage of the temperate conditions before weather more characteristic of the season took hold. Ninja Blue is my pet name for the Holdsworth-there's a long sentimental story underlying this curious moniker and maybe someday I'll share it.
Gliding through the village, attune to traffic conditions, yet equally consumed by my thoughts, we turned right into the tight and winding back roads to a warm "Alright mate!". Caught by surprise, I must've seemed unnecessarily aloof bordering on discourteous realising the second of two road riders was in fact addressing me. Tongue and manners rediscovered I managed a polite "Yourself?" before his "Yeah, not bad" concluded our dialogue.

My disconnected response left a twinge of guilt but then: I was in one of those very quiet modes that typify me-times calling for steady cadence, reflection and inner peace. Bowling along the lanes saw periodic encounter with kindred spirits before confronting Little Mountains Road. My ego whispered of how I flew up here in my teens-fixed or freewheel and mercifully powering a 79 inch gear, my legs met the challenge without hesitation despite road surfaces resembling treacle toward the summit. Unusually, body and soul felt no inclination to cruise beyond 20mph throughout our journey.
In retrospect this was just as well, entering another twisting turn and chasing onward I was greeted by a group of children playing in the lane. Given these paranoid times, I was reassured to see them so carefree. This was diluted by their desire to dart back and forth across the narrow stretch of road. Mercifully, a cautiously driven Renault MPV had tempered their passion for this curious game of dare, though my right hand hovered over the brake nonetheless. A quick kick of the transmission saw us steal a march on potential chaos. Clocking up the miles, I'm starting to notice small flaws in the build. Nothing monumental but the budget Stronglight crank shows discernible flex under load. Credit where it's due, everything turns smoothly and reliably enough and given the Holdsworth will be hibernating through the winter months upgrades are unnecessarily indulgent... Unless something irresistible presents itself at the right price.
Elsewhere the Teenage Dream is entering the second phase of its makeover but this has introduced a wealth of complications. It was an oh-so-simple recipe, purchase carbon fork, Woodman sealed bearing Aheadset and suitably refined bar and stem. Teenage Dram brought well and truly into the 21st Century...Then along comes chrome. Not just any old chrome mind, oh no. 531 race blades and a threaded steerer. This saves a good wedge of cash and worthy components from languishing in the spares drawer.
It's been seventeen years since I bought anything sporting chrome-the Teenage Dream's winter sibling had a fully chromed uni-crown cro-moly fork. Objectively, chrome plating is an awful process to subject delicate,precision components and thin walled frame tubing. I'll concede half-chrome chainstays are very alluring but this exterior beauty comes at a high price....Involving acid baths and other brutality, it's a process Dr Crippin would approve of and not the sort for a beautiful bicycle frame. Before any plating is added, substantial amounts of metal are stripped from the tubes ready for polishing. Later stages involve plenty of dunking in acid and other toxic brews before passing through a neutralising bath in the hope of purging any remnants. Any traces left here will result in internal corrosion and ultimately frame/fork fatigue.
Decorative chroming by nature is notoriously thin, made worse by modern platers forgoing the protective copper layer. This leaves a porous surface and the steel beneath vulnerable to rust-especially in coastal regions. Because paint doesn't magically stop where the chrome starts, finishers employ acid etch primers to cajole it to the slippery surface but longevity is poor and the paint ultimately recedes. Columbus strongly advise against it- ironic given most Italian marques sport acres of it!
Knowing this, why then am I still lusting after a pair? Well, £55 for 531 with a sloping crown is too tempting while allowing the channelling of precious resources into other projects. That said, the merest hint of a price hike will see me running to contemporary carbon faster than a tot with grazed knees to their mother.

Knock on Wood

Influenced by wood's widespread popularity at this year's Eurobike and coinciding with the successful retrieval of a Bob Yak trailer specific skewer from storage sees the resurrection of these bespoke Maple wood fenders. Originally designed and built for my beloved Ilpompino some three years back, they became redundant when I felt compelled to run tyres twelve millimetres wider than the 28mm profile allowed. Fast forward eighteen months and their warm, tactile colour coordinates beautifully with the Teenage Dream's rich, luxurious green livery and there's just enough clearance at the fork crown and rear triangle.
Form and function extend the bike's horizons beyond October's end but I'll stop short of running it through the purgatory of the meaner months characterised by salt and slush. However, there's no sense in performing these adaptations until modernisation of the front end is complete-namely carbon fork, Woodman headset and a befitting bar and stem. Extensive upgrades are heavily reliant upon publishers cheques fluttering through the letterbox.

Project Road Path has reached the heady heights of decal design and I've agreed a price with a local graphic design company but our old adversary, fiscal restraint means the deal will complete come September's close. I had also toyed with the idea of making the pilgrimage to Cycle 2009 at London's Earls Court but having just returned from the enormity of Eurobike, will pass on the smaller show this year.
Preparing the Univega for the fall has seen not only pad upgrades but new levers and cables too. Changing a set of pads takes around fifteen minutes tops, allowing for any last minute fettling. However, somehow the nylon cable pulleys had deformed at the nipple rendering them useless after fifteen years loyal service. Shimano Ultegra have taken their place and this evening's wet blast through the lanes suggests they're an excellent pairing, although the lever's lighter action required a short period of adjustment. Repeated unravellings of the flamingo pink bike ribbon over the past six months have finally taken their toll. Electrical tape has come to the rescue, keeping it presentable enough until I can settle on a replacement-the smart money's strongly favouring Specialized's Roubaix wrap.

Adding insult to injury, gremlins also appear to have worked their mischief on its Basta dynamo lamp, melting the internal circuitry! High power NIMH and Lion rechargeable systems offer fantastic, retina burning performance but nothing compares to the convenience of a hub dynamo set-up-lighting's on tap with no charge or run times to constrain riding pleasure and there's something deeply satisfying about generating your own illumination. I will email Mr Hunt, our local Recycle agent to see if he'll supply a replacement in exchange for a small donation. On the subject of recycling, constructive vandalism sees this this tired Raleigh mtb frameset complete with misaligned rear triangle reincarnated as a headset crown race setting tool and work of modern art. The tubing was so thick as to tolerate MIG welding and bereft of my beloved pipe cutter, reducing it to useful scrap required an hour's intensive hacksaw surgery.
After some deliberation, the bottom bracket area characterised by a very worn, oxidised crankset has a certain artistic quality. A lick of paint and polish will see it transformed into a very fetching piece of sculpture...Albeit more out house than penthouse!

Showtime!

Friedrichshafen,approximately fifty kilometres from the Austrian border in southern Germany plays host to Eurobike-Europe's largest cycling exhibition.There's something for everyone whether utility/leisure rider, road racer, track ace, tourist, time trialist, trials rider or tandem stoker. Electric bikes were heavily represented as an emergent and ever refining mainstream market. Some of us may well scoff but if they re/introduce a new generation of people to two wheels and bolster cycling then they have my quiet respect.
Elsewhere, retro was definitely the order of the show which heaved under the weight of leather bar wrap, saddles and accessories. Interestingly, high quality faux leather may well steal a march in the coming year given it requires nominal maintenance- dirt/stains simply wiping clean. I found myself particularly drawn to one exhibitor's bar wrap that looked great despite bearing the brunt of several seasons use and surviving a nasty spill into the bargain. Allegedly it changes characteristic according to conditions-cooler in the heat, yet offering tenacious grip in the cold and/or wet. Chrome is cool again and not simply among the Italian marques. Jamis had a couple of very sweet looking fixers with half-chrome stays and fork blades, although I'm underwhelmed by cable clips which scratch paint, trap moisture and ultimately encourage rust. Wood proved a very popular fender material with various larger manufacturers and small scale artisans proudly showing their wares. Fixed remains an established niche however, sub groups are definitely forming in the same sense mountain biking broke into cross country, downhill, trials etc.
The world and their mother appeared to have a fixer in the range from cynically adapted road framesets with track ends still sporting the full compliment of cable guides, carbon fibre track thoroughbreds to those following the road path tradition with sensible clearances and proper rack/fender mounts. Reynolds 525 and 631 cro-molys rubbed shoulders with Tange Prestige as typical, better quality tubing amongst the production builds-principally because their material composition is better suited to high volume production methods. However, there was also a healthy smattering of Columbus and more exotic tubesets mingling amongst 7000 and 6061 series aluminium. Cinelli and a few others presented bikes with traditional, one inch, threaded steerers but I dismiss this as little more than a quirky, promotional stunt rather than a serious indication of their wholesale resurrection by the cycle industry. That said, improved spares availability would be a godsend for those of us with older but very worthy machines in the fleet.

Anyone doubting sex and glamour's capacity to boost sales need only cast a casual eye over the stands adorned with beautiful young women in various stages of undress, the greatest titillation provided courtesy of those wearing only body paint. Being a respectable medium, I can't post those so you'll have to settle for these models on the Kellys stand.


Now, excuse me I've to purge this bag load of festering clothes accumilated from my week away....

Dusk Duties and The Dubious Delights of Time Trialling

Continued refinement sees removal of the left hand brake lever, substituted for an orphaned silver end plug found languishing on the workshop floor. Some experimentation with a cheap but not so nasty alloy bottle caddy saw me revert to the lighter and arguably nicer nylon model which at least accommodates a seatpack, no matter how minimalist. The breakthrough came courtesy of this clever little Bor Yeuh mount, clamping to the saddle rails and accommodating two cages either side. However, closed cage designs like the silver Nitto are best as ultra modern, open ended designs such as the tacx allow bottles to escape over the course of a mile or two. A stainless Salsa offering will take its place.This configuration still precludes the use of a bigger seatpack, leaving me with three options (a) mounting the trixie tool piggy-back on the the cage (b) carting it around in my jersey pocket (c)forgoing it altogether in favour of Gerber's mighty cool tool which fits comfortably inside the tiny Lezyne pouch.
Our second Sunday outing found us caught up in the excitement of some time trialling-the notorious Colchester Rovers Abberton ten mile course-a circuit with some sadistic little climbs. Fixers were a conspicuous niche' characterised by unbranded compact geometry framesets made from space-age composites. Some competitors seemed completely oblivious to traffic, cyclist or otherwise and the arrival of a race Marshall saw one rider stop dead without even the most cursory glances over her shoulder-nearly resulting in our collision!
Cross but composed I continued, only to encounter another Marshall yelling times at me, clearly oblivious to my lack of helmet, race number or other identifying marks. Another competitor, a friendly fella aboard a geared specialized began quizzing me about the route. My response was to smile, wish him every success before taking the long, straight road home, picking up the pace so as not to give the game away.
Trailer tugging is one duty I'd avoid on a fixed. Clearly spurred on by sunny skies, Joshua urged me to take him out on the tag-along for what would become his longest ride to date-a circuit of twenty-two miles to Mersea Island. Now, twenty odd miles is a nice jaunt-nothing for experienced riders to write home about but a very long way for little legs. To his credit and two rest stops he managed to pedal for the greater part. Indeed, the first stop was prompted by my need to adjust the hitch. Lowering it by a few centimetres has transformed the handling, giving a very planted feel and improving captain and stoker confidence-especially on long, winding descents. Cheaper hitches lack refinement-ours isn't too bad but I'll tighten handling yet further with the introduction of rubber bushings....

Maiden Voyage

Sometimes getting things done requires a sense of distance. Taking my own advice I spirited myself away for a few days in Norfolk-a region of the UK known as East Anglia notorious for being flat as the proverbial pancake. That said, even in Norwich the fixer scene was conspicuous by it's absence- a shame not least as I spotted the perfect graffiti backdrop for fixer photo-shoots.
Internet thieves have temporarily foiled my plans to purchase the seductive wheelset with large flange hubs so I commandeered another set, otherwise perfect for the build on Thursday morning. Older frames can spring surprises and final preparations demanded judicious filing of the ends to accommodate modern axle diameters. Gearing is now a moderate 79 inches courtesy of a 48 tooth front ring and 16 tooth EAI superstar sprocket-ample for bombing along the flat yet merciful in the hills. An uncharacteristically lacklustre Miche chain has been replaced by a substantial silver KMC offering which lacks the consummate refinement of some-especially the upmarket half link variety but enjoys phenomenal lateral rigidity, meaning transmission braking/track standing is laughably easy. Fitting some micro LEDs, a twenty two function computer capable of damn near everything bar making the tea and with the obligatory multi-tools, patch and compact camera kit slipped into the seatpack we were ready for the off...
Swing a leg over the top-tube and from the first few pedal strokes it's obvious why these now comparatively rare bikes were so popular back in the day. Short 16 inch chainstays deliver punchy performance whether sprinting away from the lights or powering along the open road. Steering is quick, yet predictable trickling through town or cornering hard on long, winding descents. 531 might no longer be the benchmark tubeset for quality lightweights but superior build quality compared with some modern frames confirms the old adage that craftsmanship, not materials maketh fine frames. For all the period fork's charms, I strongly suspect the modern, carbon replacement enhances the ride quality, delivering smooth passage over rougher surfaces while shaving a few precious grams into the bargain.
There's no trace of power robbing flex when climbing out of the saddle or dancing on the pedals, although I tip the scales at a relatively modest 70 kilos so can get away with using old fashioned square taper bottom brackets paired to modest cranksets. Stopping for some mid ride photos revealed the stem slightly misaligned but easily rectified using a 5mm Allen key. Thanks in part to a beefy chain, dependable transmission braking left the Miche calliper with relatively little to do, although it's proven a worthy stopper and in time, upgrading the pads will undoubtedly sharpen performance. Proportionally short in the torso, the Holdsworth feels overly generous in the top-tube but sliding the saddle forward compromises a good fit, placing me further over the bottom bracket into the bargain. This has the positive side-effect of increased power delivery, although I might purchase a slightly shorter Nitto stem when funds allow.

I long ago ceased talking in terms of complete and final builds given all my machines are, to some degree works in progress and subject to constant evolution. Upgrading to a larger and more practical wedge pack has necessitated removal of the Nitto cage and carry bracket so I'm returning to the hydration pack until a suitably paint friendly clip-on cage comes under my radar.
