Rings & Ratios









My Univega’s gearing has always been something of a compromise, since 2017’s new paint and 1X9 makeover. A 34-tooth ring and 11-30 cassette would’ve been too low.
The 44x11-28 gives a range between 103 and 40.5 inches, which is generally practical for road duties, although, I’ve missed the additional torque offered by the 30- tooth sprocket. Especially when climbing a 1 in 7 and battling a headwind. Plenty of the latter, this past fortnight, or so.
Having just replaced the chain and cassette, buying another would’ve been silly, so I turned my attention to the front ring. 94 BCD…Nothing suitable “in stock” but a witching hour wander round the web, unearthed a black 42 tooth Talon for £9.99.  Apparently, these had been purchased from the distributor, in huge quantities and originally retailed at £35 apiece.
I was relieved to discover the old Shimano ring’s mounting hardware released with minimal effort. Moreover, though most patterns are accurate these days, I was pleased by the Talon’s fit. Anti-seize on the crank bolts, snug tight with a long 5mm Allen key-sorted.
Gearing now ranges from 98.3 and 38.6 inches without major jumps (38.6, 45.1,51.5, 60.1,67.6,77.3, 83.2,90.1, 98.3).
Arguably a 40 would’ve been better still, offering a 36.8-inch bottom gear. However, I’m not going to lose any sleep over it and will probably switch to a 11-30 cassette, next time round.
Continuing this theme, I’ve been fortunate enough to receive some lovely Genetic Tibia track cranks (and Tibia 7075 T6 ring). The cranks are JIS (Japanese Industry Standard) rather than ISO. Indeed, to my knowledge, this is comparatively rare. Though not overly problematic in the general sense, its worth noting that ISO tapers are slightly longer than JIS. This means you will need to buy another bottom bracket, to achieve correct chainline.
I was sent the 165mm arms. 5mm shorter than the System EX Track https://www.sevendaycyclist.com/system-ex-crankset , I suspect these were selected because of the road bike designation. My working fixed has a relatively tall bottom bracket, so less problematic (The original build had 175mm arms) but shorter arms provide additional cornering clearance on a conversion. I simply raised the saddle by 5mm to compensate.
Shimano’s UN55 is ideal (read all you need) for these duties. Inexpensive, the sealed cartridge bearings have been known to reach 10,000 miles, before slop sets in. The existing unit is still in rude health.
However, rude, agricultural language followed when I tried to remove the long standing, and very likable System EX. Self Extracting crank bolts are an absolute godsend. Univega and working fixed do not feature these, but their cranks are seldom removed.
Save for bottom bracket replacement, and periodic re-greasing of the bolts. On this occasion, after 29 years, my Sugino crank extractor finally died. Stripped tool threads meant it couldn’t divorce arms from tapers.
Enter this cheap, but cheerful X tools replacement, which arrived the very next day. Credit where due, it did the job handsomely. Nonetheless, prising those cranks from their tapers, still required copious amounts of penetrant spray, a very long 8mm Allen key and the sort of primal grunting more commonly associated with a labour ward.
Now, I don’t grease tapers but the bolts themselves were given a liberal helping of Park PPL-1. Ditto the reinstated ISSI pedals. The 44 tooth Genetic ring keeps gearing at 78.3 inches.
Taller than text book perhaps but avoids knee trouble, yet tall enough to dodge comical, warp-speed spin out along 1in7s. The new setup weighs 717g (48g heavier than the System EX) but I’m suspecting there will be other, tangible benefits…

Coming Together






The kind folks at Ison distribution www.ison-distribution.com generously dropped me two of these lovely Genetic (Campag homage) seat post binder bolts yesterday (19 and 22mm just in case). Seizing the moment, I gently manipulated the frame’s ears, applied some composite friendly grease to bolt and post before introducing said components at their correct nm. Some folk still regard torque wrenches as a new-fangled luxury but in my book, lying prone in A&E while an overworked and undervalued nurse plucks shards from one’s buttocks is extremely undignified and totally unnecessary. Emblazoning my moniker along its top tube, fiddly bits are finished and with freshly herded goodies, my ferrous friend can resume secure hibernation until spring while I address pressing business matters and chart long, slippery outings aboard suitably dressed Ilpompino and Univega.

The deskilling debate has been hotly contested in many quarters with equally compelling contradiction. Traditionally this has referred to the labour market, primarily in relation to automation and manual labour. However, it appears increasingly prevalent in other spheres. I was somewhat gobsmacked to hear a police (traffic) officer remark that once someone has successfully passed their driving test; they are by default competent and capable users of the public highway (!) This contradicts widespread driving instructor/examiner conviction that such assessments are simply to ascertain someone is safe to be allowed to operate said vehicle(s) unaccompanied.

London’s seamier districts have always been awash with the unlicensed/uninsured and otherwise illegal drivers. However, toward the end of my twelve years spent navigating the capital on two-wheels, standards of PSV (Public Service Vehicles) operation had become obviously dilute to counteract declining numbers. This new breed of operator often substituted skill and courtesy with a deadly cocktail of elephantine ignorance and aggression toward smaller craft. I even recall the story of one, high on cocaine and deciding his passengers would benefit from a more scenic commute through suburban Kingston-Upon Thames (!)

Far from engaging “Victim” mode, I’m advocating for the re-establishment of “Road craft” whereby we have a collective responsibility to adopt a sense of greater humility, while continuously developing our skills and shedding this corrosive them/us tribalism. Aside from the (very real) fear of their driveway resembling a motorcycle salvage yard, my parents weren’t the least bit hysterical about a strange and irrational interest in middleweight motorcycles running in parallel with that of lightweight bicycles. Rather, they preferred to stress the importance of having a car licence-if for no other reason than to appreciate driver perspective and therefore, perceive potential hazards before they arose. Bottom line, I’m pro cycles but only have a pronounced allergy to stupid/ignorant/myopic humans, whether they be commanding car/van/bus/truck/horse/yak or indeed motor/cycle.

Against this backdrop, I am slightly perturbed by the notion of the UK’s sixteen year olds being able to drive unaccompanied on public roads, albeit behind the wheel of a heavily restricted vehicle. Now (before I’m mown down by an entourage of irate parents defending the civil liberties of their offspring) this has always been possible here under P class-trikes powered by engines no larger than 50cc. I can also appreciate why these micro-vehicles would seem preferable to little darlings terrorising commuter towns/estates astride sports mopeds, bereft of exhaust baffles (in the misguided notion such unleashes extra dobbins!) However, these do teach observation/road craft, contributing to an elevation of driver standards.

The Netherlands and to a lesser extent, Denmark are hailed as pinnacles of achievement when it comes to systems of integrated transport but in common with other social phenomenon, notions of being able to prune and re-pot in the UK is extremely naïve, failing to recognise the pronounced differences in public psyche.


Now, time I was charging some high power commuter lights and replenishing tired AAA cells, lest I fall foul of the fuzz, or worse still, become a statistic on tonight’s moonlit meander.

Tales of The Unexpected


As promised I have swapped to the magnesium bodied keo type Genetic courtesy of pattern cleats with a whopping nine degrees of knee-friendly float. Not the most obvious companions for a tubby tourer perhaps but they're something different for the summer months. On our first late evening saunter I stood mesmerised by this majestic sunset when the screech of brakes and splintering of wood tore through our serenity. A group of kids had over cooked the bend in their ageing Peugeot with the obvious consequences.Given the occupants' hasty exit and camouflaging of said vehicle(lack of insurance or similar documents being the obvious motivations) calling for assistance was pointless and frankly, I was just glad to be observing from a safe seventy yards. Darkness is now arriving with little warning, so I've been taking this opportunity to put some LED systems through their paces. Arguably a steady evolution but USB rechargeable models pretty much dominate the market, boasting commendable outputs and run times. Ideally suited to desk bound commuters and freelancers like me, dry cell models boasting thirty plus hour run times from single Cr2032 or AA batteries retain the trump card when touring and/or on long haul audax duties but with prices tumbling and technology improving at a comparable rate, who knows what we'll see in the coming twelve months.

Competition, most notably from China has driven quality to the point it's genuinely difficult to find bad models and these Revolution flash silicone LED lights are prime examples. Commanding £9.99 a piece and boasting a prodigious ten lumens (max) at the front; six the rear, build quality rivals, if not shames designer brands. Monocoque construction offers a genuinely superior grasp of oversized bars and seatposts with visibility nearing three hundred and fifty yards on a clear night without being lost in the neon confusion that characterises our urban landscape. Ultimately, finite five hundred charge life cycles might deter some but with run times close to eleven hours in economy settings, they'll still return two years faithful, service.
However, the charge cables are hopelessly short, especially for those of us refuelling at towers, (as opposed to laptop/notebook) but otherwise I'm genuinely smitten.
Some equally fetching computers from Raleigh's RSP brand have fallen into my eager mitts recently, the most notable being this wireless computer/HRM combo complete with crystal clear display and pretty much every function aside from cadence and tea making. Accuracy seems bang on, buttons are user friendly in gloved hands. My one minor gripe concerns the Heath Robinson handlebar mount. Arguably very secure in situ, installation proved fiddly in the first instance and a few spare cable ties would've been welcome too. Mother Nature's effortless transition toward autumn sees me washing Gore Tex and similar technical apparel in preparation for the cooler, changeable yet deeply enticing sepia season. Riders seeking to beat the early morning chill without resorting to winter weights training gloves should look no further than these BBB Race shield. Polyamide/Polyurethane mixes are hardly exotic but wash well and keep windchill firmly at bay. Extensive reflectives make all the difference when signalling while the rubberised palm and digits ensure excellent all weather control. Dexterity is sufficient to allow roadside adjustments, pannier rummaging and even unhindered photography.
Speaking of fettling, the Feedback sports chain gauge has presented the Univega's hard working Gusset chain with a clean bill of health. A mere .2mm wear in twelve hundred unforgiving miles is testament to their build quality, although good transmission hygiene shouldn't be overlooked. Predominantly fed on a diet of wax lubes, I'm confident of reaching 2,500 before .8mm signals retirement, although 0.06 will hail the ordering of a successor to keep the drivetrain healthy.
So then to our fetching Klein road frameset. I had hoped to bring you a full photo love-story makeover but alas, the edited highlights will have to suffice. Given a thorough vapour blasting, the owner elected an equally enticing blue, complete with sparkle lacquer topcoat. Since the star fangled nut remained lodged in the steerer, it was feared the intense curing temperatures would cause havoc, thus calling for two-pac. However, closer inspection revealed it was metal and so a false alarm. Aluminium isn't the easiest of materials to re/paint since the non ferrous tubes can generate imperfections in the final curing stage but this jewel-like effect is genuinely flawless.

Another customer opted for "Kawasaki" green with sparkle topcoat, both finishes illustrating the quantum leaps in powder coating since the early days of basic primary colours.

Riot & Revolution

Unless you've been living in some muddy backwater, starved of Internet or similar modern communications, most will be aware of the "rioting" which spread like wildfire across the UK's major cities. Debate rages along two overtly simplistic models-"system" (instigated by poverty and neglect) or mindless criminality induced by morally bankrupt "youth". In reality, academic/moral arguments are overridden by devastation on unprecedented levels for many people. Cyclists and cycle retailers were sadly, if perhaps predictably targeted because of high and easy resale values. Participants in the frenzied chaos could simply hop aboard and sprint away into the night with no thought to the feelings of their rightful owners but then thieves lack the basic values of mercy, empathy and compassion. Rioting in response to colossal injustice(s) is one thing, wanton aggression and consumerist looting are quite another. The loss of stock, spiraling insurance premiums and cost of re-fitting can be ruinous-especially for already squeezed small businesses. While left and right of the political spectrum spout rhetoric, supporting your local bike shop and refusing to buy those suspiciously cheap Cannondale touted on eBay/street corner lock ups are small, simple but positive steps we can all take.

Gone are the days when budget shoes meant patent leather uppers that roasted feet within an inch of their lives and parted company with the sole at the first enthusiastic yank on the upstroke. Memories of mid-ride rest stops, being ushered through to the beer garden with our bikes by landladies only too happy to fetch washing up bowels of cold, refreshing water in which to soak our feet once we'd ordered a hearty meal and promised not to interact with families and similarly respectable patrons... Time RXT might retain the faux hides but sport plentiful mesh for consistent, cooling airflow while acres of Scotchlite detailing are perfect for extended summer playtimes or soldiering on through a dry December's gloom. Thermoformed footbeds are marketing speak for insoles that mould to the rider's feet but in fairness do so in a matter of rides and while hardly exotic, reinforced nylon soles promote excellent power transfer without painful hot spots and seem genuinely hospitable to most standard Look/SPDR pattern road cleats. Mesh is a double edged sword though and overshoes are a must in anything heavier than a passing shower. Twenty minutes and they're saturated, demanding eight hours at room temperature to resume an arid and wearable state.Continuing this theme of misty-eyed nostalgia come these rather fetching handlebar and stem from Genetic. Beautifully finished and modestly priced, they're supplied here in the UK by ison distribution and perfect for older road and touring bikes. Common to most contemporary quill types length is limited to either 80 or 100mm but meets the needs of most riders sitting either side of average. Standard (26.0) clamp diameters make sense but riders unable to part with their favourite 25.4s can use one of Nitto's high quality shims. Will Meister has some (http://www.hubjub.co.uk/)


So to something home grown-but definitely not herbal. This here's a titanium brake bolt designed so older framesets can enjoy the pleasures of dual pivot braking without the pain of drilling fork crowns and seat stay bridges. Made in Bristol from 6A14V (an alloy of titanium, aluminium and vanadium) it measures 73mm long and is cut to Shimano RX100, R450 &R650 patterns but also entertains some Tektro and Miche. Fitting is simply a matter of removing the OEM bolt and slotting the aftermarket model in place, remembering liberal licks of Ti paste to prevent galvanic corrosion-especially on daily drivers. Contrary to claims from clubroom oracles, excessive "whip" has been a moot point and I've not so much as lain tools to it in three weeks and 280 miles.


Elsewhere, the otherwise dependable Veloset computer seemed unduly affected by electrical interference.Replacing both head and sensor batteries restored reliable and consistent readings. The eagle eyed will note the return of my once grey Look pedals from 1991. This was in the interests of putting those Time RXT through their paces and rewarded with higher cadences, more efficient power transfer not to mention red faces as we hurtled past some dyed in the wool types despite hauling several kilos of kit in the mighty Knog Dry Dog pannier. However, just as soon as some Keo pattern cleats arrive, I'll opt for these Magnesium bodied Genetic, shaving a few grams and improving ground clearance into the bargain. Much as I like the cleanliness of wax type lubes, I'm running perilously low on White Lightning's Clean Ride but remain convinced there's a few similar types languishing somewhere in the garage. What they lose to wet types in staying power, self cleansing types won't turn to a cannibalistic grinding paste when things turn gloopy.


In amongst a wealth of tatty exotica arriving at Maldon Shotblasting and Powder Coating came this surprisingly sound Klein road frameset. Aside from some unavoidable little scrapes its original "Angry Custard" yellow livery seems remarkably well preserved. Not sure what the Klein's new clothes will be just yet but hopefully I'll return with a photo love story in the coming weeks...
