Torque Talk

The puncture season has resumed with vengeful blisters thanks to some otherwise superlative Specialized training rubber that goes like the clappers and feels notably narrower than their 23mm profiles suggest but proved the proverbial pig to persuade aboard common or garden Mavic MA2s without exploding thumbs and snapped tyre levers. Further upgrades include the much-revered Thomson post.
A Saturday afternoon characterised by deeply debilitating heavy showers in dispersed with high winds led me to contemplate my powers of persuasion, removing the necessary point two of a millimetre. Thirty minutes concentrated sanding and periodic checking and a lick of this Juice Lubes Bearing grease saw it slide perfectly inside the seat-tube with no evidence of stomach sinking slippage over the past thirty miles. My only regret is not seizing the opportunity before. The product in question is formulated specifically for bearings, subjected to a completely different set of stresses compared with their automotive counterparts-hence why in many contexts, automotive greases are unsuitable for hubs, bottom bracket and headsets. The ingredients are something of a mystery, giving little indication of its compatibility with carbon/composite components but experience suggests a polymer base, equally suited to preventing galvanic and other corrosion between non/ferrous interfaces.

Quietly smug, the Altura rack bag and resurrected Pro-Lite saddle assumed their rightful places The Thomson’s forward facing curvature is perfect for smaller/riders seeking to place themselves over the bottom bracket shell for increased power and in this context it has also corrected the handlebar reach, greatly improving comfort over prolonged periods-particularly when hunkering low on the drops.
Juice ceramic lube seems a good bet for smooth transmissions too. It’s made from a blend of high quality base oils with baron nitride-a synthetic compound similar in properties to graphite. Marketed as a summer-lube it doesn’t overly attract dirt and resists seasonal showers without demanding reapplication but be sure to wipe the outer link plates on a weekly basis. Unlike traditional wet lubes, it doesn’t overly attract grime and means that pretty blue/pink/tricolour track chain will retain its looks-so long as the “Little and often” principle is maintained. Performance seems better than expected off-road- just so long as conditions fall between Death Valley arid and Mumbai monsoon.

Not so many moons ago, torque wrenches were very much the preserve of the professional workshop but as carbon and other composites have become commonplace, the notion of setting components by feel is rapidly becoming as archaic as simple rope tests to ascertain frame alignment. Unlike space-age materials, the trickle down factor hasn’t reached tooling but this little CNC machined beauty from Effetto may well be the alchemist in this sea change. It measures a mere 16.5cm long and costs a whopping £ but this pales into insignificance when dealing with top-flight components-wrecking a full carbon frameset for the sake of a couple of hundred quid is false economy an good tools always repay their investment… So long as you don’t lend them out (!)

Most manufacturers, especially the major players have carbon sussed and modern manufacturing techniques mean its unlikely to break but nipping an alloy cradle too tight could well result in a nasty fracture- is it really worth the risk, much less the expense on a saddle consuming the lion’s share of £120? So, back to this elegant piece of Italian engineering…Accurate to 0.5nm the price includes a wealth of attachments fit for tackling most components aside from more traditional 8mm crank bolts-we’ve got 2,2.5,3,4,5 and 6mm Allen keys, T20, T25 Torx and an assortment of flat and Philips head screwdrivers). These simply plug into the magnetised head. Turn the knurled sphere anti/clockwise to adjust torque-cross reference with the laser etched settings integral to the handle and happy fettling!

Now to some software. Remember those Altura Summit I introduced in my last entry, well turns out they’re really very, very proficient for general riding thinks to superlative ventilation, low weight and hardy materials. Taking the scenic route, involving deserted houses and bridle path long since reclaimed by nature, they’ve laughed at ferocious foliage, wash and dry beautifully. Being primarily an MTB garment they’re nice for touring and general riding but offerings from the like of Endura translate better to urban fixer applications thanks to closer cut, better insert and pocket configuration. Their relatively thin insert feels very comfortable-at least in terms of padding but the silicone leg-grippers could be more tenacious, allowing the garment to bunch up painfully around the crotch. Mercifully, other brands fit perfectly, thus resolving the problem. Despite globalisation and the fluidity of cultural exchange facilitated through the Internet, it is interesting to note alley cat events haven’t caught on to the same degree here in the UK. There’s been frisson of activity time and again and Bob Jackson offers a 631 Fixer frameset with this moniker.Retro has been debated many, many times both here and other column inches. Personally, I like the opportunities it presents to obtain products-or should we say reproductions long since banished to obscurity but it has to be said there’s an underlying sense that we, as a nation-possibly as a global village are being consumed by the desire to hark back to a mythical, romanticised construct of the past or bygone era. I recently happened upon this road path bike while walking through a seaside town. The owner advises it’s a 50’s Ephgrave that was bought during his national service and later re-sprayed a pink by himself courtesy of a homemade compressor. Look closely and there’s some obvious distortion (crash damage?) of the head tube, chrome has long since left the GB stem while teeth are notable by their absence on the chain-ring but that aside, it remains an interesting machine and one the owner had an extremely fond bond with. Tales of track racing, long training runs from London to Norfolk, home-made stainless steel toe-clips and other fascinating details-he’d even used the final drive chain from a Honda 90 motorcycle in place of an inch pitch or 1/8th track offering!
The omnipresent spectre of scandal surrounding European racing from the Giros to the Tour De France have petty much eroded any interest beyond vocational in the professional scene. Without being overly simplistic, the hug amounts of money involved is conducive to institutionalised doping but the authorities appear to have made it their life’s work to conclusively prove Armstrong and more recently Floyd Landis as persona non-grata. Armstrong is understandably distancing himself from Landis who is widely regarded as a bitter, disgraced drugs cheat but some are saying (with some conviction) should the allegations have any foundation, Armstrong’s achievements are then tantamount not to the greatest show on earth but arguably the greatest fraud in sporting history. Armstrong is a very shrewd, self-aware businessman first and foremost-he just happens to ride a bike and will protect his interests at all costs. Similarly, I’ve no idea whether the bike-doping revelations with motors in the bottom bracket shells (supposedly) providing additional assistance on the climbs are little more than a rumour or elaborate hoax but it wouldn’t overly surprise me. Jacques Anquetil once laughed at the suggestion the tour was won on Evian. Equally, cycling is giving other sports from cricket through to athletics a convenient smokescreen to hide behind.

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.....
