Fork, Rotors Action...











 After some foraging, I’ve everything together for Ursula’s front end upgrade. The Project 2 fork sports a crown race, has some corrosion inhibitor sloshing around its inner sanctum, and the TRP Spyre SLC calliper bolted to the IS adaptor. Following the “use what you have” mantra, I’ve blasted the remainder of some heavy-duty PTFE spray inside.  

The sort that forms a thick, protectant layer and can also evolve into a fat-ball, causing sticky control cables. Great for protecting electroplated frame/fork ends, derailleur cable guides that run beneath the bottom bracket shell, trailer hitches and locking mechanisms, garage rollers. Jobs, where grease is too heavy and traditional maintenance sprays, are too easily dismissed by wet, wintry roads.  


Indeed, a couple of teaspoons of 10w40 motor oil coursing through the tubes would do much the same job, although, in this instance, I’d need to deliver it via a syringe-messy but again, dirt cheap and very effective.   


Now, I’d been believing, nay convinced myself that the RL340 wasn’t compatible with disc brakes, so needed an RL520. However, closer scrutiny of the Tektro site contradicts this (I wanted to swerve travel agent or similar adaptor), so hopefully, that pans out, in the real world. I have a sliver right-hand RL520, but cosmetic symmetry is also important.  


The rotor in this instance is an auction site special. I was curious as to its performance and durability. In any case, I have a Clarkes unit sitting in the brake spares box...Somewhere. The transplant will take place at a more convenient time, probably when the weather turns a little less wintry and I can switch to the fixed for a while.  


However, I’ve gone the slow and steady route to cut down on time and potential snarl-ups. Tucked away in Ursula’s Deore crank, the Torque 7 tool is remaining rattle-free, and pleasant to use. The magnetic components mean everything’s still together. There's been a faint hint of taint but nothing a quick once over with an oily rag won’t arrest convincingly. On the one hand, I’d expect that, given the price point but reassuring and the tool itself is genuinely much nicer to use than I was expecting.  


The Schwalbe Land cruiser has been another pleasant surprise. Traction and rolling resistance have been more convincing across the board, even along untreated, slippery backwaters and at 70psi.  Puncture resistance is lower on their scale than say the Marathon plus but again, thus far no unpleasant surprises. During one freezing ride, I went for Ursula’s bar con, ready to drop down a couple of gears, in preparation for the climb that would take me past the poultry processing plant-an eerie pulsing hulk, especially at 530am.  


Nothing, it was if the lever had frozen solid. Thankfully, I wasn’t in an overly tall, knee popping gear, so cruised my way to the summit. Over the top, the Microshift brifter behaved normally once more. Weird. It did remind me of tales pro mechanics told of treating chains with anti-freeze, during winter cyclocross races.     


For months, the UK media has seemingly been obsessed by whiteouts, “thundersnow” and the general second coming of the ice age. Now, I’m no stranger to spiked tyres and really rate them, for tackling winter’s more extreme conditions. I was very intrigued by Kenda Klondike, but these aren’t so readily available in the UK and then I happened upon what may be the holy grail. Schwalbe Ice Spiker Pro. I’ve been impressed by the Schwalbe Winter TESTED: SCHWALBE WINTER SPIKED TYRES (sevendaycyclist.com) and the upgraded Schwalbe Winter Plus.  

However, the Ice Spiker Pro is reckoned to be the “turbo of spike tyres” with a maximum of 402, yes 402 spikes. These are made from tungsten carbide but coated in aluminium. They still weigh 997g apiece (which is still lighter than the Schwalbe GT365 TESTED: SCHWALBE MARATHON GT 365 BICYCLE TYRES (sevendaycyclist.com)

Big Chill AKA the Spikes Stay!














No, I’m not predicting a boiler breakdown, which like many other mechanicals, usually strikes at the least convenient moment. I’m referring to the crashing temperatures and “white-outs” (a seasonal obsession with some sections of the UK’s mainstream media, presumably to distract from the consequences of Brexit. I’m starting to notice shortages of fresh produce in supermarkets and suspect this will become more apparent since fresh fruit and vegetable produce cannot be stockpiled.).  


Until Wednesday, local lanes have been predominantly cold, wet and greasy but nothing a big section slick, such as the Schwalbe Kojak couldn’t take in their stride.  

Nonetheless, I knew Murphey’s law would see temperature plummet the moment I switched the spikes in favour of slicks. A sharp reminder came when navigating the serenely silent stretches. Starry skies, glistening asphalt cluing me in and sure enough, around the bend- black ice.  


A momentary loss of traction was quickly reclaimed by the Marathon Plus’ Tungsten carbide spikes. Seeing the depth of the shimmering ice looming ahead (and clinging to the bodies of solitary passing vehicles), urged caution. I have also chosen to resurrect the ORP Smart Horn TESTED: ORP SMART HORN (sevendaycyclist.com) to alert pedestrians/dogwalkers of my presence. For the most part, friendly “Good morning/Afternoon/Evening” works fine. However, cold weather and winds can impair this, so a friendly upward prod of the “Whale tail” should sort this.   


Sticking with the Univega means sodden backsides are a distant memory, thanks to its full-length chrome plastic mudguards. These also keep the bike markedly cleaner, thus extending maintenance intervals. I was surprised to discover some superficial brown taint on the nickel-plated areas of Ursula’s Shimano M540 pedals. Especially since I didn’t notice any salting beyond the main roads. Nothing a quick shot of GT85 GT85 ALL PURPOSE LUBRICANT (sevendaycyclist.com) couldn’t smother.  


Nonetheless, a weekly wash down is advisable to remove any salts/similar corrosives and while stodgy wet lubes are an obvious choice, give a chain’s side plates, derailleur jockey wheels, and cage(s) a clean rag cat-lick. Purging this unsightly excess evolving into a gritty grinding paste.  


Really impacted stuff is best blitzed with a solvent-based degreaser, and fresh lubricant applied. Chill and shorter days mean convenience is sometimes king. Strong solvent degreasers, including Weldtite Jet Blast WELDTITE JET BLAST DEGREASER | cycling-not-racing (sevendaycyclist.com) make this a more time-efficient process, when the temperature’s tanking. Those looking for a more frugal lube stripper might find Muc-Off Drivetrain Cleaner MUC-OFF DRIVE TRAIN CLEANER | cycling-not-racing (sevendaycyclist.com) .  

For really deep cleans, I’m fond of Green Oil Agent Apple Extreme Immersion Degreaser TESTED: GREE OIL AGENT APPLE EXTREME IMMERSION DEGREASER (sevendaycyclist.com) . Don’t be fooled into thinking vegetable-based solvents are mild and friendly though. These can be just as, or more flammable than their petrochemical counterparts.  


Testing aside, I’ve never felt the need to remove and immerse the cassette (although this is certainly an option and something I’d be inclined to do, with chains-if only to protect the frame’s finish from accidental spatter). However, I do whip the wheel out before basting the product on, angling the cassette toward the tarmac, so solvent runs away from the hub and therefore, rubberised components, such as seals.   

     

I’ve also purchased another UN300 bottom bracket, to subvert potential supply problems nearer the time, when its existing UN55 starts grumbling. I occasionally toy with the idea of taking the Hollowtech route, probably reaching for the Shimano Zee crankset, since that’s “in stock”. However, I have the ratios right and it makes sense to run the existing setup, while its practical and economic to do so. I was going to order a few gear inner wires but found four, while rooting around my storage boxes.  

Cursory inspection, using this Kranx Chain Wear Indicator KRANX CHAIN WEAR INDICATOR | cycling-not-racing (sevendaycyclist.com) suggests the chain’s still in pretty good health, reckon I’ve got another three, maybe four hundred miles before substitution’s needed. Little n’ often maintenance is the way to swerving most problems.  


However, the COVID19 pandemic continues to rampage through the country. It has reached the point where the capital’s firefighters and police officers are now driving ambulances. I knew the relaxing of conditions for Christmas day would induce another pronounced spike in infection rates and envisaged the army’s engagement. However, I hadn’t envisaged the present chaos, which is both surreal and unsettling.
