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.

Reflections & Relentless Rain











 Water, Water Everywhere but Not a Drop to Drink. Flooding has been this winter’s narrative and the lack of flood defences here in the UK would seem to be making matters worse. However, the less extreme ends of this are great for assessing the capabilities (and sometimes shortcomings) of everything.  

From waterproof, breathable clothing to mudguards, waxes, detailing products, bike washes, lubes, and of course, electricals. Leatt has sent me their Endurance 2.0 Jacket, which is aimed at cross-county mtb/gravel audiences but in my experience, makes the transition to general road duties very well.   

The jacket is a “super lightweight” model that packs down very compactly. Leatt reckons inside a jersey pocket, and I’d broadly agree, depending on how large your pocket is. No issues with the old-school, deep terrace typeIt’s a Nylon/Elastane “rip-stop” weave that forgoes a laminate for improved ventilation and features a DWR (Durable water repelling) windproof and stain-resistant outer shell. Knitted panels also feature knitted paneling in the back and panels for improved ventilation. 

The former also features a poacher’s type rear pocket. Me being me, I would’ve preferred a breast pocket too, for a compact camera etc. However, it’s a feathery, racy, close-fitting cut for minimal flutter and this second pocket with cargo would pull, thus impairing the fit etc. That shouldn’t be read as only being suitable for summer weight/long-sleeved jerseys. I’m pleased to report ours is roomy enough for the winter-weight jersey cum jacket genre too.   

I’ve gone for the blue but black and rust are the alternatives. The zipper is also waterproof, although I would’ve preferred a bigger tag, even allowing for my not-so-dextrous dominant index finger. I’ve done my usual, cable tie zipper tag extension, solving said problem.   

Packable garments are arguably the most practical options for changeable conditions, although I’m still a big fan of the 2.5-layer laminate type when it’s predictably wet and indeed cold. Talking of which, I also received some more lubes.  

This time from Blub’s range- a ceramic and a wax, which are cleaner running preps designed for drier weather. Obviously, it's most important to test them in the conditions for which they were designed. However, I am also interested to see how products like lubes behave in wider contexts. After all, conditions can change throughout a ride. How practical is a lube to reapply? Does it wash away, how good are its corrosion-inhibiting properties? How much grime does it attract etc.   

One of the very appealing features of these two is their rapid curing times- allegedly two minutes apiece for both, which is on paper as practical as you’re likely to find. Seems a little longer in practice. That said; I’ve been applying in 2/3 degrees. Yes, I know there are still pour-and-go formulas but even after you’ve drizzled them into the chain’s inner sanctum, you’re still needing to wipe away the excess before hopping on and scooting offI’ve left the fixed and Ursula’s curing for a day, primarily since I applied having purged their drivetrains and given both bikes a seriously good sudsy bucket wash and wax.  

One thing led to another, and I whipped this 28mm Schwalbe One 365 up frontAll weather/ al conditions tyres are a big ask and to some extent, there’s always an element of compromise somewhere. In my experience, with lighter, swifter tyres it tends to be puncture resistance.  

The Schwalbe weigh in at 332g apiece, less than half the weight of The Pirelli Angel ST Urban Tyres Pirelli Angel DT Urban Tyre | cycling-not-racing (sevendaycyclist.com) and indeed, the super dependable Kenda Kwick Journey KS Plus KENDA KWICK JOURNEY TYRES | cycling-not-racing (sevendaycyclist.com) . However, these Vittoria Rubino Pro Control Graphene 2.0 Vittoria Rubino Pro Control Graphene 2.0 | cycling-not-racing (sevendaycyclist.com) are a much closer comparator and 5g apiece heavier. Will be interesting to see how the Schwalbe perform across the board and compared with the Vittoria and to a lesser degree, the Maxxis Refuse 700x32c 60 TPI TR Folding Maxx Shield Tyres MAXXIS REFUSE TR FOLDING TYRE | cycling-not-racing (sevendaycyclist.com) 

I’ve also been further contemplating the benefits of hub transmissions and bikes built around them. Genesis Day One employs a double-butted aluminium alloy frame and Cro-moly fork and is built around the humble 8-speed Nexus hub. Cable-operated discs might lack the low maintenance bite of hydraulics but are easy to service and repair.  

Budget but a practical workhorse cum commuter. Nice enough but not so pretty you’re petrified by the thought of tethering it to hardy street furniture with a decently stout “fuck off” lock. Long story short, I’d be interested in racking up some proper miles on one.  

Another enticement, given the flooding and generally adverse conditions are hub dynamos that can be serviced “in the field”.  By that, I really mean models that can be stripped, bearings replaced and regreased without going back to the factory. Interestingly one side of the Alfine hub dynamo Shimano Alfine UR700 Hub Dynamo | cycling-not-racing (sevendaycyclist.com) can be accessed and the bearings replaced.  

While the SP series of hubs have been impressive despite some extreme and persistently wet conditions, I’m tempted by the KASI FS DynaCoil CL/D6 units which are designed to be opened using a 36mm headset spanner. I’ve had 20,000 miles plus from the PD8 before the sealed bearings got sloppy. However, given the miles Ursula and fixed gear trainer rack up in foul weather, the ability to strip, clean, and rebuild the hub, without dismantling the wheel is a definite draw
