Gravel Rash












No, I’m not referring to a fast and painful encounter with terra firma (although back in the late 90s, I sported acres of asphalt and slag burns). I am of course referring to the genre of off roading aboard rigid bikes with cyclo cross DNA, bigger clearances and more bottle bosses.
 

This sense of escape is the same as that first imagined as a callow youth, reading mountain bike magazines during geography classes. Back then, I had no money. These days, projects need to pay for themselves and any new one, MUST coincide with schematic and continuous clear outs.
Enter this frameset. It’s a 19inch 631 Dawes from the early 1990s, complete with 1- inch threaded fork. It belonged to Paul Vincent and run by him as a cyclo cross bike, hence, the cantilever mounts were moved to accommodate 700c wheels.
It had been refinished in a rather fetching, although slightly battle-scarred grey. The project brief is to build a fat tyre, pared to the essentials 700c gravel flyer for virtually nothing.
Reclaiming space and cash is imperative. Otherwise, thee comes a point where friends’ garages and loft spaces have also been colonised…Next thing you know, they need these spaces back and, you’re presented with an almighty storage crisis. Things turn decidedly awkward for all concerned.
This sense of panic also means, you cannot separate what is valuable (whether that’s measured in sentimental, or monetary terms).   
I’m a creature of sentiment but there comes a point where three, maybe four saddles, is fine, ditto six sets of (different) condition specific tyres. Ten saddles, 15 sets of tyres and it’s time to rationalise.
Context established, little surprise that I dropped by Maldon Shot Blasting & Powder Coating http://www.ctc-powder-coating.co.uk/  for a chat. Graham seemed quite excited by the project. He gently steered me away from a classic red and toward a candy teal.
Candy finishes though beautiful, are tricky to apply and, even applied by the most experienced sprayers, there can be some very slight variances in the overall effect. I was told by Paul, that the frame had been powder-coated. Hence, I was expecting it to need a dunk in the methyl-chloride tank. This softens the paint, before it can pass to the iron oxide cabinet.
Closer inspection and a knowing sniff; revealed it was our old friend, wet-spray 2K. Hence, having masked the threaded areas, Graham whipped it into the iron oxide blaster. It took twenty minutes to remove every. last trace. However, good, sympathetic preparation and a correctly keyed surface is essential. No dings, dents, or similar imperfections, which was pretty much my expectation.  More next week…
 
Like big tyres? Well, I reckon Vee Tire Co Zilent https://www.sevendaycyclist.com/r  give Schwalbe’s long running and justly revered, Marathon Plus https://www.sevendaycyclist.com/schwalbe-marathon-plus-tyres  a good run for our hard earned. For me at least, working bikes need to be practical but also fun to ride.
Arguably, if a bike isn’t fun, then its not actually that practical. I’ve had a quick switcheroo of my Ilpompino’s front tyre, exchanging the Continental Contact plus https://www.sevendaycyclist.com/continental-contact for the lighter, faster rolling 42mm Maxxis Roamer https://www.sevendaycyclist.com/maxxis-roamer-tyres
I’m a sociable loner and an introvert by nature. Characteristics, which are frowned upon in a society, that favours extroversion. However, many, introverts, myself included, are very capable of holding our own in a professional context. I can interview people and network with suppliers all day long.
Cycle and motorcycle touring teach a myriad of skills. Self-sufficiency and resourcefulness being the most obvious. Forging constructive relationships quickly is another. Crashes can be painful.
The best maintained machines can fail unexpectedly. The skills to repair that broken rack are academic, if you can’t persuade a local mechanic, or blacksmith to lend you their welder. Then of course (As my late father was fond of pointing out) you might want to eat!
No, I didn’t learn to read people’s minds, or perform some Vulcan-esque mind moulding technique. (More’s the pity!). Nonetheless, I can identify whether someone’s intentions are good, or otherwise.
Working with models demands the ability to quickly put people at, and moreover, maintain that ease. My shoots are renown for being very chatty. Unlike extrovert personalities, outside of these contexts, I require a lot of time to myself, contemplating ideas and mentally recharging.
Most recently, I’ve worked with Tom Collins, seen here modelling our Seven Day Cyclist T shirt and the lovely, ultra-professional Amy JR Jones. Amy and I hard originally planned a duo-shoot, with an aspiring male model but he backed out, without notice.

Cream











Paint freshly cured and blemish free, my Univega's frameset grew accustomed to its new identity at centrally heated room temperature. I headed north on other missions and awaited the arrival of those chain-ring bolts for the 1x9 conversion. Several days hence, those bolts had arrived...
Long drives can leave me feeling wired, so I promised myself, I’d “Just do an hour”; treat the frame internally, get the headset, bars, stem, bottom bracket etc in…
Three hours later, I was a lot further along but reaching that dangerous tipping point-the one where thought processes become addled and mistakes made. At 1.30 am, I flopped into bed and resumed building after eight hours rest.
Everything breezed together with liberal helpings of fresh grease and minimal faff. On the subject of grease, I’ve been suitably impressed by the longevity of Green Oil eco grease that remained pretty conspicuous on fasteners and bottom bracket threads alike some months in. http://www.sevendaycyclist.com/green-oil-eco-grease  
Full-length mudguards certainly help but, I was also pleasantly surprised to discover a decent layer of Muc-Off grease still adorning the Stronglight Aheadset bearings. These had been pretty much untouched for two years.    
Rebuilding is an ideal opportunity to give components and accessories a really thorough scrub. Mudguards were purged of wintry sludge; corroded “stainless” fasteners were replaced, re-greased and snugged tight. Many miles in, its KMC X9-ept chain http://www.sevendaycyclist.com/kmc-x9-ept-chain was now well past the first flushes of youth and signalled another enforced break, while waited for its SRAM PC971 replacement to arrive.
Puncture season in full swing, I switched my attention to salvaging tubes. Having discovered my ‘cross inspired fixer’s front tyre pancake flat, I changed the tube, rounded up some other casualties and patched them for spares duty.
Two patches is my limit. Those sporting more; or larger lesions are decommissioned and reincarnated as top tube/chainstay protectors, headset or seat collar boots.
During the Univega’s makeover, Graham asked if I would drop by and strip his scabby old tart- a much loved, though world weary mid-90s GT Timberline.
It would’ve been ungrateful to decline, so, needing a break from the screen I popped in midweek. Two hours, one tin of penetrant spray and some nervous moments later, everything (including a seized UN30 cartridge bottom bracket!) relented.
Frameset bare and ready for the stripping tank, I turned my attentions to the Timberline’s grungy Alivio groupset. A liberal helping of Fenwicks’ FS1, some warm water and furious scrubbing later restored it to a socially acceptable and basically serviceable state.
While kinder to user and environment than my old friend, methyl chloride, the wispy vapour emanating from the other tank, always reminds me of the transporter scene in David Cronenberg’s visceral reworking of “The Fly”. Several minutes later and it had done a decent job of softening and partially stripping the existing finish.
Dredged from the chloride tank, things are basically dry. This one leaves a slightly slimy layer behind, which demands a few minutes longer in the blast cabinet.
After a few false starts, every last trace of residual paint and stickers were gone, leaving only a faintly dimpled, primer friendly surface behind. Graham’s going the blue route and has plenty of choice at his disposal.        
Elsewhere, there’s been a sudden swing to wintry weather. I’ve been thankful for my ‘cross inspired fixer’s quick, though dependable handling while chasing along lanes carpeted in thick slush.


Fixed offers that extra bit of feedback between tyres and surface. The ability to ease off gently against the transmission to slow, rather than pulling the front brake and being spat off is a definite plus!

Kitchen Sink Drama






Kitchens double as fantastic workshops-fresh running water, kettle food, TV/radio and similar creature comforts. Returning from the midlands with new laptop, I decided there was no better way to start the week than reassembling my beloved Mk2 Ilpompino.
Having carefully reintroduced headset cups, seat collar and bottom bracket shell, everything came together pretty effortlessly, although by midday focus was waning on account of telephone calls and encroaching hunger. By this point, only the front brake needed dialling in but I’d earmarked other, pressing deadlines for the afternoon. 
Tuesday was deeply frustrating, spent awaiting a courier and responses to urgent emails-neither of which arrived until late that afternoon, though thankfully I managed to keep a 4.45 appointment. By 1800 the disc was sorted and home brewed frame preserve sloshing inside the Ilpompino’s inner sanctum.
New seasons’ clothing and lighting needed putting through its paces and I don’t require enticing where kit testing’s concerned. I was also pleased to discover decathlon had sent me a G-Eye2 escape under warrantee. This seems a marked improvement over its likeable predecessor. Fittings/accessories are GO-PRO pattern, so thus far, everything, including the weatherproof casing plugs straight on.
A quick, cursory play later, I mounted it on the Ilpompino’s handlebar extension bracket, engaged lights and headed out. Just as Tuesday was concluding on fairly positive notes, while grinding along a greasy, dung strewn gradient, we sliced through a cowpat heavily impregnated with hedge clippings…
The Vittoria voyager hyper unleashed a loud petulant hiss, blowing raspberries with every revolution. Despite being narrow, large trucks often take this route to small industrial units, so a suitable clearing was imperative if I wasn’t to become another piece of roadkill.  
Finding a safe, sheltered spot, I rummaged through the wedge pack. No CO2 inflator!!!!...A wave of panic subsided upon finding the Specialized midi pump, spare tubes and my favourite BTwin tyre levers.
The eerie silence was broken by a woman’s voice. “Excuse me, have you got a puncture?” Despite the Sigma Evo Pro lamp’s considerable power, I couldn’t pinpoint her location but presumed it must’ve come from the cottage opposite.
“Yes, but its fine-thank you” I replied, an early 80’s Godley and Cream track “Under your thumb” suddenly filled the backdrop as my imagination went into overdrive. I wouldn't mind but there's still a few weeks until Halloween.
Even in standard mode, the Sigma Evo Pro’s has sufficient bite for spirited backroad scratching and I was particularly grateful for its prowess as I removed the front
wheel, extracted the wounded butyl and began scrutinising the Vittoria’s casing for embedded sharps.
Ten minutes later, wheel reinstated with a useable 60psi, I resumed my twenty mile loop. Petitioning the god of punctures with prayer seemed to help. Kenda thorn-resistant tubes are my first line of defence, rolling resistance is more apparent given their relative heft.
However, their valve stems are too short for deep section rims, so I may opt for something impregnated with green goo if this scenario becomes more prevalent into winter.  Time to replenish the otherwise superb faux leather Mpart bar wrap. Hmm, what will it be?...

Transformation Complete









Having left Kushi KA for servicing/MOT testing, Meg the magic (Nissan) Micra spirited us to Maldon Shot blasting & Powder coating for the grand finale’. Upon arrival, Chris had already tended the affected areas with Metafil-an aluminium based filler that seems much sleeker than thermal putties, although care is needed to avoid generating air bubbles since these can bleed through during the final curing phase.

Perhaps unsurprisingly given its age, there’s trace, corrosion induced pitting along the inner, drive-side chainstay, thankfully long dormant and before my adoption. This superficial scarring won’t present in the final colour coat, nonetheless, Chris leaves nothing to chance and gives said section a final, precautionary tickling in the glass bead cabinet.

Three minutes later, we’re ready for masking and that all-important zinc phosphate primer. Pedants might advocate chromates but the former is much kinder to personnel and planet while performance differentials are negligible. Indeed this brand cures with phenomenal, seemingly elastic tenacity given ten minutes at 200 degrees whereupon Chris graciously offers to create an exotic two-tone effect with no cost implication. However, accepting such would be tantamount to bladder milking, so we commence with RAL5024-pastel (sometimes called “French”) blue.

Being an electrostatic process, there’s no wastage and he achieves comprehensive, even coverage in five minutes, lovingly hanging it in their walk in oven for a further ten. At this juncture decals can be applied and sealed under a two-pack lacquer but I prefer a quiet, mysterious air. Speaking of which, there’s no need to clear coat-a finish of this calibre will look resplendent for many years. However, an acrylic was applied since opportunity presented itself.

Unlike polyesters, there’s no risk of crazing but acrylics cannot be sprayed to warm surfaces; hence said chassis sits patiently for twenty minutes beforehand. Lacquers appear white for sprayer convenience but form a glossy invisible barrier within the oven. Job done, we are reunited and homeward bound. Once again, I’d like to thank Lee Cooper (www.leecoopercycles.webs.com) and MSBC (http://ctc-powder-coating.co.uk/) for their remarkable generosity of spirit and obviously, taking such good care of my beloved frame.  

In the days since, I’ve reinstated the sealed square taper bottom bracket and am reflecting on headsets while doing some post (successful pass) MOT sill surgery- Kushi’s are sound, though demanded sanding and marine primer TLC to halt the silent killer’s relentless advances during the grottier months. Now, off to play with some 700x29 tyres!
