Boosting my Fibre Intake










 No, I’ve not upped my six Weetabix breakfast habit, rather carbon fibre/composites. As I’ve said before, beyond a certain time, an idea can become the only idea. In this instance, we’re talking carbon fibre cranks that a well-known online auction site’s algorithm reasoned I would be seduced by.  

Sensibly priced, 172.5mm long, and square taper, they’re clearly made in the Far East, which in some respects goes against the European narrative. I can always switch to either of the Campagnolo cranks and the rings too. Besides, they were from a reputable, long-established, Yorkshire-based supplier.  


Talking rings, I decided the OEM 53/39 pair were best consigned to the spares/bin. Worn rings aren’t going to do anything for shifting, or drivetrain healthChain ring bolts proved a little arthritic and stubborn- I'd toyed with the idea of introducing some penetrant spray, but a longer 5mm Allen key broke them free.  


Traditionally, I’ve always mounted rings with grease to get them nice, snug and weatherproof. Marine greases being my specific default, although I’ve also been known to employ those fortified with our old friend/foe, PTFE. In a pinch, a syrupy wet chain lube, or 10w/40 motor oil will suffice. Lithium types are durable but best avoided unless bolts and rings are of the same material. 


I’d no intention of re-using them but kept them by, since you never know...This presented ideal opportunity to thoroughly clean and inspect the arms and spider. These were in great shape. I gave both a quick waxing and placed some Zefal Skin Armor ZEFAL SKIN ARMOR ROLL | cycling-not-racing (sevendaycyclist.com)  on the arms where there had been some faint misting in the lacquer-heel marks. Prevention is always better than cure and now was the time.  

I had this nice, shop soiled 53tooth Middleburn ring. So began the hunt for a suitable 36, 38, or indeed, 39 tooth inner. I thought I’d struck gold, rifling through one of the spares boxes but it turned out to be 130bcd. Then along came this NOS 42tooth 10speed Campagnolo Record. Bankrupt stock, so very keenly priced. 42 sounds a bit old school, dare I say passe’ but being as I’ve gone the 14-24 route at the rear, I’ll probably get more use out of a 42, rather than 39. Decision made.  

I’ve reached for Peaty’s Bicycle Assembly Grease PEATY'S BICYCLE ASSEMBLY GREASE | cycling-not-racing (sevendaycyclist.com), since it’s a good all-rounder with decent staying prowess. I had contemplated using thread lock but though I’ve needed to snug chain ring bolts every so often, in 37 years, I’ve never had some slacken to that extent. As a rough and ready, Cro-moly bolts should be tightened between 12 and 14nm, aluminium alloys 8-9.  


I’d been experiencing some discomfort with Ursula’s Respiro saddle, so decided I’d switch back to the Selle San Marco Concor Super Corsa. This also revealed the saddle was slightly misaligned, doubtless explaining the original discomfort. Either way, the Super Corsa provides a little extra support. I whizzed the carbon-railed Selle Italia Turbomatic Gel Flow Team atop the fixed gear winter/trainer’s inline Genetic SyngenicTEST & REVIEW: GENETIC SYNGENIC SEATPOST (sevendaycyclist.com) post, raised it by a few millimetres and saved 63g into the bargain. I also noticed the rear cradle bolt had slackened a little, which may account for a slightly disconcerting and intermittent phantom creak that snuck in a week previously.  

 

While I was there. I decided now was the time to switch the KMC S1 for the brands’ Z1I’d toyed with leaving the S1 in situ, changing when the present helping of ultra-stoical Motoverde PTFE Chain Lube Motoverde PTFE Chain Lube | cycling-not-racing (sevendaycyclist.com) needed replenishment. The Motoverde PTFE Chain Lube is not of the “top up” type, rather requires stripping “dinner plate” clean before a new application. It was a post-ride switch, and the weather was turning a little bandit, so I dismissed the Z1’s factory lube with a rag dipped in white spirit, rather than something potent but requiring cold water rinsing.  


I also noticed some premature wear with the Stronglight headset, which I attribute to a rogue unit, bought online from an unknown supplier, rather than from a regular, reputable one. Mutters something about all that glitters, false economy etc. I’ve gone for an FSA Orbit MX, also with cartridge bearings, rather than another Stronglight. I’d run an Orbit with bottom race cartridge bearing and caged balls up top, trouble-free for several years, so I’m hoping it’ll be a similar story. While I await its arrival, I’ll end here with a book review  The Road Book 1989 | cycling-not-racing (sevendaycyclist.com)
