Spring=Tweaks & Trails


 







Sometimes it's not the nice new shiny kit that brings the most joy, nor a personal best, or an epic ride. Sometimes, it's getting a wayward, recalcitrant component to behave. Ideally from the comfort of home-an outpouring of relief usually follows the latter scenario.  

 

Recent little victories include getting Ursula's Microshift bar end shifters to play properly with the old girl's STX and Tiagra mechs, upgrading Denise's Hollowtech II preload to an aluminium alloy 10mm Allen key, meaning I can largely forget about the little plastic tool bit that invariably gets lost behind the workbench, or similarly inaccessible area of your workspace.  

 

Last but not least, there's the wired Remote for the Magicshine Ray2600, which means I can whip the power up and down more readily on the fly-great for exploring the lanes in the dead of night. 

 

After an unexpected cold snap prompting me to default to Ursula and the spikes, things thawed a little and I revisited the idea of Denise and gravel tyres. I’d stuck with the Continental Pure Contact, which have proven themselves incredibly dependable in all contexts, meaning I could just hoss along, confident I’d return from a ride without flatting-particularly welcome when pressed for time. Extra UK have sent me some Pirelli Cinturato Gravel M (700x40c).  

 

These are a tubeless ready mixed terrain gravel tyre designed for mixed conditions, wet, or dry-hence their appeal. The Cinturato Gravel M employ the Speed GRIP compound, which promises mechanical resistance, chemical grip, and similarly important, impressive puncture resistance. This is a nylon belt that runs bead to bead, rather than just the centre strip, so I’m hoping they deliver, not least since hedge cutting season has returned with a vengeance.  

 

They were surprisingly easy to sweep aboard the Ryde rims-read thumbs, no tyre levers, pressure ranges closely mirror those of the WTB Nano WTB Nano TCS Tyre | cycling-not-racing, as does the tread pattern. They’re 14g heavier at 513g, but still a very respectable, dare I say reassuring.   

 

Given a marked shift to milder conditions, I also took it as my cue to switch Ursula back from the Schwalbe Ice Spiker to the Continental Cross Kings. Doing so also revealed a little slop in the Hollowtech II bearings, which may have also contributed to temperamental shifting- out came the Oxford Torque R10, which tackles most jobs nicely, including those with higher torque fasteners-no issues removing the crank pinch bolts. A judicious turn of the M20 preload and these were nipped snug, then fully home with a torque wrench...Time to hit the lanes and trails   

 

Wouldn’t you know it, the front mech was misbehaving again. I released a smidge of tension from the STX’s pinch bolt Ursula’s front mech, then released the Microshift bar end lever’s tension fractionally- bingo up and down without missing a beat. Nothing serious, but these units seem more highly strung than their Centos 4700 counterparts. I also raised the saddle by a few millimetres, which seemed optimal.  Talking of tools here’s Steve’s review of the Oxford Torque Slimline 12 https://www.sevendaycyclist.com/oxford-torque-slimline-12-co2-multitool 

  

The milder conditions have allowed ¾ lengths It’s not been sufficiently mild for short sleeve jerseys and arm warmers, but layering is the key to enjoying early season and autumn.  

 

The ability to whip a layer on, or off to counter a sudden change in weather is good at any point- micro jackets will protect against unexpected showers and sudden, chill winds. Lighting is also very necessary since while nights and mornings are getting longer and arriving earlier, it's easy to get caught out. Six months or so hence, I’m suitably impressed by Shimano’s most recent incarnation of their Nexus Dynohub.  Shimano Nexus DH-UR700-3D Dynamo Hub | cycling-not-racing 

  

Though less mucky than midwinter, the early season still calls for regular bike cleaning. Oxford Products have sent me this huge cleaning buckets, which makes cleaning a big fleet (and indeed, other vehicles) a more time-efficient task.  

 

The bucket has a grit grate to stop gritty, muck stuff being redistributed around the bike (or another vehicle), there’s also a wash mitt and microfibre cloth. I’ve already given the KA and Micra a good wash n’ waxing to purge the witches brew of slurry and road salt and the 20-litre bucket makes the job much quicker-no need to run indoors to fill mid-way through.

Cranksets & Calculations











The Deore Crankset arrived and with a 32tooth front ring and 12-28 cassette, gives a range between 29.4 and 69.44 inches. A little low at the upper end for tarmac terrorism and catching riders, but plenty of torque for trailer towing and gravel stuff.  


Ideally, I’d be looking towards something in the high 70s. Will stick with it for now, unless a suitable, closer spaced option presents. 11-25 would give 33.0-74.9, which is arguably a better option. I took this opportunity to replace the chain and deep clean the drivetrain, since the existing KMC had done 1,000 plus. Besides there’s no sense in prematurely wearing cassette and new ring. I also noted that, despite the nickel finish and being fed wet lubes, it had become quite stiff and showed the ominous orange taint.   


Wintry conditions largely gone and while waiting for the new crankset, I whipped the Univega’s wheels out, given the frameset a more thorough waxing of its intimate areas and switched to the Schwalbe Billy Bonkers.

  

This also presented the ideal opportunity to give banish the congealed gloop, clinging to the cassette and Sun Race derailleur’s jockey wheels, using this Squirt Bike Cleaner Concentrate. Thankfully, the oily residue had done a good job of preserving the finish, so no call for the M16 Ride & shine M16 RIDE & SHINE | cycling-not-racing (sevendaycyclist.com) 


I’ve been getting the miles in on the fixed. Switching the Schwalbe Marathon Plus for the 42mm Continental Contact was a sensible move and I ordered replacement ceramic pads for its TRP Spyre stopper, so they’re in stock, when replacement’s next due.  


The Zefal Z11 bag is proving a very useful addition. Minimal sway (which is unusual for the bigger models, especially those tethering to the post via a single strap). The larger breed also doubles as a decent mudguard, protecting saddles and buttocks from cold, wet, slimy stuff.  


On the theme of transmissions, I’d returned from a ride, intending to simply tweak the chain tension, when I discovered some issues with the Fix-G HALO FIX G TRACK HUB | Seven Day Cyclist Tourin Tests Commuting side of the hub. Horsef*ckers! No matter, I switched back to the Aerorage wheel, until I’ve time to assess things properly.  


Oh well, might as well, give the transmission a good blitz, then feed it Squirt Low-Temperature Wax Chain Lube. Talking of the concentrate, this can be applied neat, as a degreaser, or diluted to make a bike wash.  


I’ve decanted neat into a chain cleaner receptacle, a 30/70 concentrate/water mix as a winter weight/early season bike wash. Like many concentrates, it can be applied to (a) the drivetrain via brush/chain bath, left for a few minutes, then agitated and rinsed. Or (b) poured over parts and left marinating for a few hours/overnight. This version pours easily in cold weather-noticeably so, compared with its otherwise impressive standard counterpart. SQUIRT LONG LASTING DRY CHAIN LUBE | cycling-not-racing (sevendaycyclist.com)  


Wax formulas aren’t the obvious choice for cold, wintry conditions. Indeed, I would reserve most for spring/summer. However, this low-temperature blend stoked my curiosity. Similarly, while wet lubes are the obvious default for wet/wintry conditions, they can also attract a fair bit of gunk.  


Purging this regularly (as you should) can be a tedious chore. Ignore it and there’s a very real risk of it grinding through expensive rings, cassettes, derailleur jockey wheels (and even cages). Waxy types require longer curing times but will simply scab off when leaden with contaminants. 


No need to scrub, or clean, just apply another layer and leave to cure.   

As the photos illustrate, I’ve gone this route with Ursula’s new chain, since I was there.  Also switched back to the Ravemen CLO6 Sensored Rear Light.RAVEMEN CL06 SENSORED REAR LIGHT | cycling-not-racing (sevendaycyclist.com) Fancied a formative “shakedown” blast to see how the new drivetrain components behaved and its CLO5 counterpart needed a charge.
