Derriere Delight & Rapid Chain Consumption


 






Having switched saddles and riding conditions milder and wetter, I switched to Muffin and some fixed gear serenity before things flip flopped again. Reunited with the titanium railed Spa Aire, I was delighted with the comfort but also noted some slight slip with these Castelli Competizone Bib Tights Castelli Competizione Men’s Bib Tights | cycling-not-racing- the case with the Ergon it replaces.

With another snowy blast on the horizon, I switched Ursla from the CST Patrol CST Patrol Folding EPS Tyres | cycling-not-racing to Schwalbe’s Ice Spiker Pro Schwalbe Ice Spiker Pro Tyres | cycling-not-racing. Wheels in situ, I then decided a chain check was opportune- .75 when I introduced my more basic, nickel-plated tool. Bin fodder either way.

I had two in stock, so no issues on that front. Simply brake, prune the new and click into place with the magic link. Now was also the opportunity to expel some gunge clinging to the jockey wheels and lighter grime adorning the rings. Something also prompted me to check Denise’s KMC- said nickel-plated gauge also slid straight to .75.

Again, an easy fix, and chance to strip some residual gunk from the jockey wheels, cage and rings.  Both chains had been fed the Muc Off C3 All Weather Chain Lube Muc-Off C3 All Weather Chain Lube | cycling-not-racing . This also serves to illustrate how persistent exposure to waterlogged roads, mucky lanes, trails and of course snow and salt rapidly consume drivetrains-even with disciplined cleaning and light lubrication. Denise’s chain was only replaced in November. I subscribe to the philosophy of buying less exotic chains, since they still return a reasonable mileage and are relatively kind on the wallet when replacement’s due. Same goes for cassettes.

Rings should be fine, so long as you’re not lax when it comes to replacing chains. However, there’s an argument for investing in stainless steel, rather than 6061 aluminium alloy rings. At least on a tourer, or other bikes that do big mileages year-round. Mercifully, the Deore FC M5100 fitted to Ursula and Denise are steel, which adds a few grams but theoretically repays with improved durability.

Again, Deore is often regarded as entry-level, but the specification and performance are still very impressive. Back in the 1990s, I had high regard for Shimano’s STX & RC components, good enough for racing, but affordable and economic to replace, should you bend something beyond repair in a crash.  They key with all these things is to keep repairs, replacements and upgrades practical. Unless a gift, or passed to you at an incredibly favourable rate, bolting high end CNC machined rings on lower to mid-range cranks makes no sense.      

All this also serves as solid argument for running a fixed, or single speed steed as a primary winter bike. One ideally with full length mudguards (fenders). That said, fixed and single speed drivetrains are low maintenance, decent sprockets and chains are key, since they’re under a fair bit of strain and that’s before you throw the witches brew of wet, salt, grit and similar nasties into the mix.

Without doubt, the best sprocket I’ve ever run was EAI Superstar- a beautifully machined, highly polished stainless-steel affair commanding £45. EAI also offer a less exotic steel stablemate for £25. One that arguably strikes the best balance of value and performance on a working, or training bike.

I’m also suitably impressed by the Andel Fixed Sprocket (1/8 17tooth) fitted to Muffin. I’m not a fan of electroplating per se. I appreciate it looks pretty but I don’t like the process and acids involved. Nonetheless, Muffin’s seems to be holding up very well against the elements and offers a winter, knee friendly ratio of 67.5.

Great for a smooth, struggle-free cadence, but without going into overdrive on the descents.  As for chains, I’ve had surprisingly good results from budget KMC, such as the Z510, their higher end stainless counterparts, not to mention, the Gusset S Link and thus far, this Izumi. Once upon a time, while riding conversions I ran 3/32 Sedis, but it’s been 1 1/8th track fare all the way since I took advantage of fixed’s resurgence in 2005.

Muffin Racks up The Miles


 







Having tweaked the chain tension and tightened the ring bolts to 10nm, I was feeling more confident with Muffin and keen to gently rack up some miles to bed everything in properly and possibly reflect on further modifications/upgrades. Frankly, I’d built with everything I’d intended, rather than older parts and compromises.  Consumables such as chains, sprockets and bar tapes will be replaced but nothing major.

After some deliberation, I found myself pruning the chain by two links, sliding the frame forward in the dropouts and getting the chain play to 1/2inch, which is the textbook suggested ideal. I also found myself replacing the inner brake wire, then dialling in the TRP Spyre, which improved stopping somewhat. Presented the ideal opportunity to play with the Park torque wrench some more.  Simple tweaks can often make huge differences. I also run a little scrap butyl where the frame fit pump rests against the top tube’s underside, protecting it from unwanted rub and ultimately, paint damage.

Though the V2 was always fun and predictable, Muffin’s bigger clearances, improved lateral stiffness and general modernisations make for a very well-balanced machine with a magic carpet ride-especially with the Continental. These clearances also mean I can run 35mm Schwalbe Marathon Winter (spikes) during the darker months. Features that better suits my riding style. That said, I remain fond of the V2 and its geared, first generation Kaffenback (Think CafĂ©’ & back) cousin (which would also take 32mm tyres including mudguards). Think winter/trainer cum working bike, although some folks report theirs were reliable lightweight tourers- I can well believe it.

Talking of small jobs, shoe cleats are often neglected, and these Shimano had served me very well but were showing obvious signs of deterioration. Mercifully, the bolts, though slightly arthritic came away with a quick shot of Muc-Off MO94 Muc-Off MO94 Multi Use Spray | cycling-not-racing. I had thought one wasn’t going to budge, calling for the drill bity but thankfully this also shifted with a T25 Torx. I instated the new Leatt cleats with a liberal helping of Oxford Toque Assembly Grease Oxford Mint Assembly Grease | cycling-not-racing and torqued them to 4nm using the Velo Tool Torque Wrench.

 I’d also been keen to test the effectiveness of some degreasers on waterproof grease. Ironically, Ursula’s Shimano XT seemed slightly reticent to budge. A quick shot of MO94 helped with this reticence. Some Park Tool PL1000TESTED: PARK TOOL POLYLUBE 1000 LUBRICANT FOR BICYCLES still remained on the threads, which is impressive, since it had been a year or so since I removed them. I treated them to a modest helping of degreaser, reinstating them with a liberal lick of Oxford Torque Assembly Grease. 

Ursula and I have also been enjoying further exploratory meanders far from the maddening crowd. The CST Patrol is running behind, the Continental Cross King Black Chil up front. There’s a method to this, primarily since the CST Patrol are slightly narrower, thus giving greater clearance at the rear triangle. The Patrol are also 80g heavier than the Cross Kings and I’m wondering if this has any connection to the EPS (Extreme Puncture Safety) belt, which is 4 on CST’s scale. It also allows me to compare rolling resistance and similar performance characteristics.

 I’m genuinely impressed by both at the moment and in similar contexts, although there’s a substantial price differential between them. The Patrol (at least in 26inch guise) aren’t tubeless ready, which may be a consideration, nay dealbreaker for some. I can appreciate some very palpable advantages of tubeless setups but on balance, still prefer tubes, whether the humble butyl, or TPU.   

 Either way, both tyres are providing a dependable, compliant ride over some very badly surfaced gravel roads and farm tracks. Longer excursions also confirm I’ve got Ursula’s saddle height absolutely right.
