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.

Shakedowns but no breakdowns...


 








Forty miles in, Ursula and I were bonding very nicely. Then, to my surprise (and good fortune, since this struck 2.5 miles from home) I glanced down to discover the left-hand crank was creeping off. No 10mm Allen key on the multi-tool meant nursing us back, minimising contact with the left side. Having returned, I whipped out 10mm, 5mm Allen keys and of course, trusty torque wrench. I can only imagine things stretched during the formative outings. Pre-load faffed and ultimately everything rejoined and behaving to type, I pondered some more pre-winter prep.  

The recent wet roads had me thinking I should add a protective butyl boot to Denise’s lower headset race. I decided rounding up the tools and taking a decision from there was the best route. Before I knew it, I’d plunged in head-first and met a few surprises. The quill converter had become mysteriously stuck. Nothing a quick tap with a rubber mallet didn’t solve (although I still needed to tap the expander wedge free- a long flat screwdriver and controlled nudge from the mallet fixed this).   

Everything else came apart easily and ample Juice Lubes Bearing Grease clung to the bearings and races. Fork out, I slid the butyl over the head tube and rolled it up. Another quick lick of grease to the lower balls, I reinstated fork and mysteriously had the headset adjustment bang on first time.  

Reassembling the quill adaptor, I added some of the Oxford Assembly Grease to hopefully subvert and further episodes of stubbornness (adaptors are prone to seizing). Same went for the hardware. While the Juice Lubes Bearing Juice is a synthetic, putty type formulation, I applied a quick shot of Muc Off Silicone Spray to the underside of the tube, to help it glide over the headset.  

 

Allowing for the fact I geustimated, rather than measured the length of tube, the coverage is precisely as I wanted it and should, with the added helping of grease, lock the elements out. Lizard Skins and others used to produce neoprene covers, but unless removed every wet ride, could cause moisture to get inside.  

 

Old inner tubes are plentiful and could even be scrounged from your friendly local bike shop. It’s tempting to strip the crankset come next chain replacement and treat the axle to some Peaty’s Speed Grease (for the last word in low friction) but the Wolf Tooth is a premium blend and seems highly effective thus far. Will be interesting to see how it fares against winter’s witches’ brew.  

 

Staying with pleasant surprises, I was sent another set of the WTB Nano, not the TCS tubeless ready versions this time. Their UK importer tells me these are the 120tpi versions employing their SG2 puncture repelling belt that runs bead to bead, so will be interesting to see how they cope in this regard during the darker monthsAside from gravel and indeed “more adventurous touring” they’re also aimed at cyclo cross audiences and, given their “most conditions” persona, it’s not difficult to see how the genres ahem, cross-over. I’ve found them surprisingly good in gloopy UK mud, but again we’ll see how this translates through a mulchy mucky British winter40mm wide, they’re going to be a little portly for more traditional ‘cross bikes, which can typically swallow 32-35mm, 38 if we’re talking a slick commuting/touring tyre for off season’s road duties. 

  

Despite the rise in popularity these past twenty years, cross meets still have a very eclectic flavour. Sure, there are packet fresh disc equipped carbon fibre bling machines but plenty of traditional cross bikes, repurposed tourers and indeed, mountain bikes looping the circuits. Single-speed transmissions keep things rugged and reliable, provided you’re prepared to stick with something around 63 inches…  

 

There are a few folks who also brave it on a fixed. I can see the appeal, but as I say, very much a niche thing. On-One’s Mulo might be a prime candidate. There’s clearance for 43mm tyres without tickling the chainstays and you could either run it with a disc up front or go the old school cantilever route.  

 

The latter are again, still very popular. Lightweight, simple and still relatively effective, set up correctly, with decent quality pads and cablesStandard cables with PTFE linings and stainless-steel inner wires are good staples, although the jump between these and more elite, sometimes sealed systems, such as the Jagwire Road Elite is very palpable.  

 

Aside from the fit n’ forget weather sealing, the inner wires are extremely high quality, thus virtually zero stretch and very tolerant of fine tuning. I’ve set ours up and removed them from Ursula’s callipers with no signs of compression, let alone fraying. Braking is very progressive, stiction free, but again, I’d expect so at this end of the market and again, I’ll see what impact if any, winter has upon their stopping prowess.  

 

Transfil Flying Snakes were another solid (and much cheaper) choice on the sealed front, but fitting was more involved and cable rub could be an issue if you hadn’t used the little protectors or applied some helicopter tape to the head tube and other areas where the outers sit, or brush against the frame.
