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.

Curiosity...







Left to my own devices, I became curious regarding the new Deore crankset’s suitability and wanted to check chain length, before introducing front mech, bar end shifter and cables.

 

Off came the 1x10 deore (switched to the Dawes Edge frameset for safe keeping GRAVEL ON A DUSTBOWL BUDGET: HARVESTING COMPONENTS (sevendaycyclist.com)). Plenty of Peaty’s Bicycle Assembly Grease PEATY'S BICYCLE ASSEMBLY GREASE | cycling-not-racing (sevendaycyclist.com) graced the Shimano XT Shimano Deore XT PD-M8100 Pedals | cycling-not-racing (sevendaycyclist.com) pedal threads.  


The Juice Lubes Bearing Juice was still clinging to the Hollowtech II axle. Pleasing, given its primarily designed for bearings SIMPLE SERVICE: CUP 'N' CONE HUBS | cycling-not-racing (sevendaycyclist.com). . With the new, 2x10 Deore , I opted in favour of the Peaty’s Speed Grease PEATY'S SPEED GREASE | cycling-not-racing (sevendaycyclist.com). Everything back together and buttery smooth, 110 link chains seemed correct- no hint of straining at the lowest gears.  


Confirmed beyond reasonable doubt on the following morning’s twenty-mile test run. Nonetheless, I had plenty on, so the front mech and shifter could be fitted at my leisure. Sometimes things need to be works in progress, rather than rushed.  


Quitting while ahead some might say. Besides, the Crane Cousins sacrificed a front mech and shifter to save precious grams on their Special Products Raleigh Bikes for their epic tour...Journey to the Centre of the Earth - Richard Crane, Nicholas Crane - Google Books Ok, let’s not get too carried away...Who was I kidding???  

Saturday morning, I returned from a 430am ride and decided I’d get busy in the methodical, offer stuff up and check sense. I managed to retain the “child at Christmas” sense of urgency until 7am. Yup, that I’ll just do some preliminaries went out the window too. In for a penny... 

 

Chain split, the biggest challenge was the front mech.  


The Deore was proving a non-starter with the MPart Mount, so I decided to save time, cut my losses and reach for the STX. My hunch that the 24-year-old mech would save the day proved so. I also needed to remove the serrated panel from the rear Blumels Shiny Mudguards SKS BLUEMELS SHINY MUDGUARDS | cycling, but not ususally racing (sevendaycyclist.com) to allow unhindered cage travel. 


Cable outers cut, everything connected, I needed to adjust the travel but despite being designed for a 3x7, it slipped back and forth very snappily-without any cage manipulation. Although being a triple, I was meticulous, borderline neurotic when adjusting the limit screws.  

Having ensured it wouldn’t drop off either side, I reintroduced the Souma Leather Handlebar Tape Souma Leather Handlebar Tape | cycling-not-racing (sevendaycyclist.com), checked everything shifted reliably and popped the old girl away.


4.40am on Sunday morning, the acid test. Better quality inner wires tend not to require intervention but either way, I leave inner wires eight hours (or overnight) and then pull through once, if needed. I’d toyed with leaving things another day or so and switching to the fixed meantime but 440am came around and a shakedown ride called.  


No nasty surprises, the old STX shifted impeccably in both directions with no hint of cage rub, or similar teething troubles. That said; the Merida cage gracing the seat tube bottle boss chose this opportunity to expire- without warning. The tool caddy was ejected onto the front rings, causing a moment’s anxiety.  


In the darkness, I thought the worst-broken derailleur cage, popped chain... I had spare links and replacement magic links in the tool caddy in any case. I packed the cage into Ursula’s Axiom Ocean Wave City+ Seat Pack AXIOM OCEANWAVE CITY+ SEAT BAG | cycling-not-racing (sevendaycyclist.com) and rode home. I’d considered this Zefal Pulse Z2 Zefal Pulse Z2 Bottle Cage | cycling, not usually racing (sevendaycyclist.com) before settling on the winged carbon fibre Boardman.  


While I understand and appreciate magic links, I’m not completely at ease with them. I much prefer a pin of some description and that’s on a derailleur transmission, let alone single speed, or fixed setup.  


A 2x10 transmission has given me a range between 26.9 and 84.3 inches some added power on the road with greater torque offroad, or when a trailer’s trundling behind.  


Staying with chains, the Muc-Off Wet lube seems to be holding its own, despite rains of biblical proportions. The sort that creates deep, lingering puddles, which can conceal a multitude of nasties-potholes are extremely fertile right now.  


John Moss has been developing a mount for the TRP HYRD calliper. Although I’m not in a rush for it (am planning to fit to coincide with cable and/or pad replacement), I'm getting quite excited...
