Imperfect Match

The long Easter weekend presented the ideal opportunity to do a little snagging, some of those irksome little jobs around the fleet that were relatively straightforward but required what might be termed "quiet time" to perfect and the Holdsworth was a case in point. Being a summer build with regular component revisions, the inevitable nicks had cropped up around the otherwise flawless "old boots tough" finish. Capable of resiting a hammer blow, powder coating forms a supple, protective skin around the metal. However, in high stress areas such as the seat tube, compression of the ears caused by tightening and tweaking of the binder bolt can result in flaking, betraying the protective silver chromate beneath.
5012 is not an uncommon colour but getting the exact shade proved tricky so I laboriously mixed a perfect match from these tins and applied it lovingly to the affected areas in the gentle April sunlight. While the first coat cured, the post arrived bang on cue with these fixed lock rings. However, my sunshine turned shady upon discovering neither would come close to breezing aboard the corresponding hubs. This was frustrating as I’d timed these little jobs to coordinate-especially since the house and time were unusually very much my own. Research confirmed encroaching suspicions that Miche require a dedicated type so I dropped Company Z, their UK importer a quick email to see if they could recommend, or better still, supply me with a compatible unit. No sooner had I powered up the PC and sent the email, the touch up enamel had dried sufficiently for a second application. Pedants will note the brush just caught the binder bolt but being chrome, any excess will lift clean off courtesy of a quick scratch from my fingernail. Half an hour in the temperate spring sun and the second coat was two parts cured so I hung the Holdsworth safely on its rightful hook in the workshop. Easter Sunday’s twenty mile morning blast certainly made best use of our seasonably changeable climate and saw me questioning not only my very brave colour scheme but more importantly, handlebar positioning. Upon returning home and reflecting in the kitchen with a cup of diesel strength coffee, I slackened the stem clamp and rotated the pursuit bars downward, in a more aggressive stance which also falls more naturally to hand. A fair bit of scouring (virtually and in person) suggests the ITM Olympus aero bars are obsolete to the point where spares are literally non-existent so I’ve pandered to my urges and secured these from the helpful folk at Greyville. Elementary and moreover, secure fitting coupled with easy adjustability wins them brownie points and even the computer still works perfectly, despite being moved and now somewhat askew of the sensor. I may well bind inner tube around the arms for greater comfort and further refine positioning but they could prove the fastest 500g I’ve added to said beast. The package arrved complete with reducing rubber shims meaning they can be migrated to the Teenage Dream or indeed any other machine with standard road bars should need arise.
Some would argue there are plenty of broadly similar and therefore, ITM compatible brackets lolling about thanks to badge engineering where two, or indeed more brands are identical, save for the decals. Now, I’m a real lover of experimentation and rummaging through the spares bin can reap great reward but as the lock-ring saga demonstrates, this can be rather akin to looking for a ruby in the proverbial mountain of rocks. Reverting to the arguably beautiful Nitto combo would make good use of the Race-Stick Spinacci copies but I upgraded the cockpit in the interests of shorter reach and improved rigidity for no-compromise hammering.
Spring snagging also tackled the Teenage Dream’s rear brake housing which has always been a fraction to short, resulting in the rear calliper binding when turning the bars sharply, carving into swooping descents etc. This also presented an ideal opportunity to upgrade the bar wrap. In fairness, there wasn’t much wrong with the entry level stuff that coincided with the New Year rebirth but the measure of good quality tape, aside from the obvious comfort, abrasion resistance and style is how often it can be peeled back and reaffixed. You get what you pay for and sadly, said budget brand tore despite being very gently peeled from the bars. It now sports some curious, if strangely tactile rubberised Lizard Skins wrap. This requires slightly higher levels of concentration to apply but promises unparalleled grip-even in torrential rain and I’m really looking forward to putting it to the test. Proof of the pudding is in the next few hundred miles…

Oh For The Want Of Taste, Lock-rings and Traditional Clubman’s Braces

Spring has indeed sprung and with it, much fettling of the fleet- new saddle for The Teenage Dream, lightweight aluminium sprocket and matching Pink Halo courier tyre aboard the Holdsworth's enviably smooth Miche rear wheel. Alas, we’re missing a lock ring so the full transformation (and a colour scheme guaranteed to question my masculinity) is on hold until I can acquire some cheap but very cheerfuls. However, we’ve reverted to the super smooth and aptly monikered EAI Superstar 16tooth sprocket seeing as the opportunity presented itself.
Joshua is steadily gaining confidence with his solo but it's just fractionally on the large side and I'm now certain, with a weekend's practice on a balance bike he'd have the basics well and truly licked. Seen a few nice ones but I'm reticent to purchase given the relatively short use-span so I'd be delighted to hear from any UK based readers willing to pass or loan one to me for a modest but fair price. One incident that certainly left little to the imagination occurred while testing these courier knickers-plusses by their more traditional, English name. They’re made from a fairly substantial cotton/nylon mix complete with double seat, soft elasticated leg-grippers with world champion detailing, rear pocket and elasticated waist. Fit is snug, not quite as chic say as the latest generation of ¾ lengths but completes the period look aboard a classic track/road bike, especially worn with the full retro ensemble- Merino wool jersey, shoes and of course, cap. They’re a little warm say for the height of summer-well, eighteen degrees plus at any rate and decent under shorts are a must for longer rides. However, the material repels water better than you’d expect, fleece lining keeps early season chill firmly at bay but whatever you do, invest in a set of braces. These have become as rare as the proverbial hens teeth with the dominance of Lycra bib tights/shorts and my last pair finally succumbed to both the dreaded sag and pitted chrome disease after eighteen years service.

Out for a blast along the lanes, periodically watching the asphalt as it blurred beneath me, I eased out of the saddle ready to conquer the climb (or so I’d have folk believe) when the elastic lost its embrace around my waist, leaving me flashing a lot more than a California smile. Mercifully the woman following in her Mondeo had a sense of humour! A pair of braces was purchased online before the close of business that afternoon. Saddles are another deeply personal matter and in my experience the distinction between road and mtb is often simply down to marketing. Selle Italia’s Flite is one such design classic transcending both genres and arguably a pioneer in the popularity of titanium as a mainstream saddle rail material. The Shiver is wider than my ideal and surprisingly that of the Rolls it replaces-at least on paper (300g does not set pulses racing in 2010) but low-weight and formula’s do not maketh the perfect perch (Sliding from the nose of a classic concor model and catching my fun-sacks squarely on the top tube of my converted Raleigh fixed back in the Summer of 1990 still induces watery eyes). Faux leather covers will appeal to strict vegetarians on an ethical level and being impervious to sweat/water won’t require periodic proofing to keep the hide supple. Manganese rails are worthy enough, siblings of the Cro-moly family oft confused with more exotic magnesium. Some commentators argue this is a deliberate ploy on the part of manufacturers but first impressions seem favourable. Making no secret of my relative disquiet when it comes to the long term health consequences of regular/prolonged exposure chemically brewed miracle cleaners, let alone their effect upon seals and other, more delicate finishes I am presently putting some of this Pedros “Green Fizz” through it’s paces. The foaming formula is claimed to clean all areas of the bike safely and on any surface or material-including carbon fibre. Early indicators are positive, gently removing a healthy layer of congealed marine grease and other light road spray from the Holdsworth’s rear hub and track sprockets. To date it seems gentle to most finishes, yet not quite as potent as some made from natural, citrus based ingredients. However, the next few weeks intensive testing will provide a more accurate measure of its capabilities, or indeed limitations.
Speaking of capability, a chance conversation with a friend has introduced another engineering firm who might be willing to undertake machining of seatposts- I've found a straight-cut, polished Campagnolo Victory which, in theory at least is easier to work on. Assuming said firm is happy to perform the surgery, I'll sell the Thomson and plough monies into another project. Watch this space.....
