Logistical Redemption & Festive Threesomes









Hmm, perhaps someone in the logistics industry was reading my last post-those Tenn gloves and overshoes have just arrived-along with this Stronglight Aheadset.

Made from neatly machined 7075 aluminium, it boasts annular (as distinct from ball, or needle roller) bearings. Arguably, the latter are equally suited to touring, tandem, trike and similarly high stress applications thanks to broad surface areas.

Will be interesting to see what (if any) difference these make, especially at the lower race. I have previously employed the French marques’ justly popular and similarly priced threaded A9 model with more traditional touring builds.

Trouble free for many thousands of miles; I’m hoping this unit will follow in its footsteps. Lip seals promise similar defence against moisture/ingress but other factors; including correctly reamed and faced head tubes, sympathetic installation using stiff greases is equally significant.  Fitting’s earmarked for that quietly industrious, contemplative corridor between Christmas and New Year.

According to folklore, things run in threes. Freehub was first, headset second and this week, its otherwise dependable Dia Compe rear stoppers got the sulks and couldn’t be cajoled back to civility.

Regular readers will recall my predisposition toward front braking, reasoning that 80% of our weight moves forward. However, legalities aside; I’m firmly of the mindset that if something’s fitted, it must be functional and preferably finely honed.

Often a judicious blast of PTFE based spray while repeatedly pumping the lever cures matters. No joy…Closer inspection confirmed the frame’s pivot points were clean and completely free of corrosion. In fact, they still sported a protective layer of ceramic grease, comparably spotless springs too. Yet the left wouldn’t return for love, money or kind words… 

While having a thorough clean, sweep and tidy of the garage (as stipulated by one’s maternal figurehead during her most recent weapon’s inspection), I happened upon these wide arm units that once adorned the Ilpompino’s seat stay bosses.

Mechanical efficiency is greatly superior to low profile designs, although more extreme versions can present compatibility issues on smaller frames, especially when large panniers and generous feet enter the equation.  

Fresh cable, a lick of lube and ten minutes light fettling later they were pride of place. Reliable service resumed with discernibly superior modulation and feel-huzzah!

Talking of braking, I’ve always been a fan of the much maligned U brake. Sure, its low slung location had dire consequences for mountain bikers venturing beyond arid, dusty trails but I was impressed with their power and believed it had much wider horizons.

Decathlon would appear of similar opinion judging by their Alur 700. An unusual move since discs have stolen the show on road biased builds these past few seasons. However, this configuration was chosen to improve clearances, thus entertaining 28mm tyre sections, which can deliver a more compliant, sure-footed passage over wet, greasy winter roads. 

Suspect said stopper will require more frequent cleaning/inspection given its likely to be blasted with that slimy, sludgy and sometimes salty cocktail, mind.

Right, well my extra powerful 1700watt vacuum cleaner has just this minute expired-the fourth thing in a row (!) Best pack bags, head off to the midlands, watch some grass roots ‘cross racing and spend Christmas with very special people.
