Easter Beatings









 Easter can be a cold and unpredictable period- Good Friday in particular. March has been bitterly cold and decidedly wet on these shores. Maybe I should head off for Hungary and capture some of the country’s beauty, the Czech Republic for the Pomlázka, perhaps...Ah but here’s the thing, a lot of British people put their cross in the wrong box during a pivotal vote in 2016.  

This means travelling to other destinations-especially in a commercial context got considerably trickier. I was also saddened to learn that Moore Large (distributors) went into administration- a brutally close-to-home reminder of just how difficult the UK’s economic climate has become  


The weather has also put paid to some early-season weekend fun on The Teenage Dream and Holdsworth. I’d only washed and waxed Ursula the day before this photo was taken. A single ride through the green lanes and backroads saw her chainstay and bottom bracket region blasted with cack.  


Silver linings...Well, it proved the ideal opportunity to check (and tweak) the front mech and mudguard fastenersI also fitted the Teenage Dream’s Sun Race freewheel, rather than run the risk of the much-loved Regina BX blowing its guts at the least convenient moment.  


The Sun Race’s plated finish looks a little low rent, by comparison, but as Richard Ballantine so rightly said (in the context of derailleurs before anyone picks me up on it) better a fresh budget unit, than a top-flight model one shift from oblivion.  


Rear mech roulette lost its appeal many moons ago. Ditto spontaneous implosion of any kind, for that matterEnd of an era though. I’ve had that BX since 1991 and there’s a lot of memories woven into that. A lot of memories, hopes, dreams and indeed, unrequited stuff. Yes, that’s code for I’ve stashed it inside a transparent plastic sleeve and into the transmission parts box 


Talking of which, after several months, I’m not sure the Smanie GT137’s channelling groove is completely compatible with mine, so I’ve switched Ursula back to the Selle Royal Respiro Sport SaddleThe Smarie now ported over to the fixed’s Cane Creek Thudbuster ST TESTED: CANE CREEK THUDBUSTER ST SEATPOST (sevendaycyclist.com) to explore this hypothesis on one with a lower, more aggressive front endIf the past few rides are anything to go by, reverting to the Respiro was the right decision.


During this phase, I also noted some minor side to side slop in the Kinekt 2.1 Aluminium Suspension Seatpost KINEKT 2.1 SUSPENSION SEAT POST | cycling-not-racing (sevendaycyclist.com). This was traced to the side link bolts and easily dialled snug with a 3mm Allen key- glad I checked. It has tightened performance a notch and loss would be very inconvenient


Replacements are available and inexpensive Side Link Bolts – KINEKT Store (cirruscycles.com) but would’ve meant unnecessary time off the road. Easily avoidable too, more to the point. Note to self, check more frequently...    


Aside from the obvious-wanting to have machines at their optimum and getting the best from the riding experience, I’d argue these, and related processes of elimination also serves as a conduit for processing, and finding solutions to other, unrelated things. Including, but not limited to, financial matters, an issue at work, studies, career, relationship(s) etc.  


On a brighter note, dawn's arrival has been progressively earlier, and the cooler temperatures mean I can get more miles from the winter/early season wardrobe. The Oxford Venture Windproof Gillet has certainly earned its keep OXFORD VENTURE WINDPROOF GILET | cycling-not-racing (sevendaycyclist.com) ditto these Funkier Aqua Gents Pro Water Repellent TightsFUNKIER AQUA GENT'S PRO TIGHTS | cycling, but not usually racing (sevendaycyclist.com)  


Water-repellent tights will hold heavier rain back. Whereas I might start to feel soggy in traditional tights give an hour’s moderate rain, or persistent drizzle, I’ve returned primarily dry, given 2.5. That said a bib tight is always the best choice, since they offer better protection to the lower back and vital organs. 


I’m also thinking these retro reflective claw-type Carnac gloves were an inspired choice. Padding density is good for most riding contexts-including green lanes and light trails. The retro-reflective silver effect is great when signalling, or just being picked up by other vehicle headlightsDexterity might be an issue for some and if you’re seeking something a little less niche’ Steve found a lot to like about the 360 Dry Waterproof Gloves. 360Dry Waterproof Gloves | cycling-not-racing (sevendaycyclist.com)  


I’m still attached to Altura Night Vision. They’re starting to look a little lived in, dare we say characterful, but perform well in the waterproof and relatively breathable sense. They will also accept liner-type gloves for when the temperature’s really tanking but you don’t want too much bulk.  


Otherwise, 4-12 degrees is their comfortable operating range. Until recently, the roads have been wet enough to consume the Muc-Off Wet Lube in 280 miles, which is still very respectable, given the conditions and on par with the Weldtite TF2 Performance All Weather Lubricant TF2 PERFORMANCE ALL WEATHER LUBRICANT | cycling-not-racing (sevendaycyclist.com) in comparable settings. I’ve been traversing single-track lanes and waterlogged back roads with a bit of town work, for good measure. In common with others, it needs to be stripped with your anti-lube of choice before reapplying 


This is good practice with lubes generally. However, some more traditional wet types are receptive to a quick “cat-lick” before being topped up. More sophisticated formulas tend to react and become mucky drivetrain-gobbling potions. Not what most of us would consider desirable.  




Weldtite very kindly sent me some of their bike cleaner concentrate to brew up my own strength bike washes and of course, to use neat-as a degreaser.

Stems & Other Pleasant Surprises












This Vecnum freeQuence Suspension Stem arrived to distract me from the UK’s unbraked descent into terrifying in chaos. It’s a spring/elastomer parallelogram design, intended for riders between 50 and 120 kilos (110 to 264 lbs). There’s more than passing similarity to the Kinekt Suspension Stem KINEKT SUSPENSION STEM | cycling-not-racing (sevendaycyclist.com) that Steve and I remain fond of, too 

However, at 285g a fair bit lighter, and adjusting the tension doesn’t require opening the stem or swapping springs (not that this could ever be described as a hardship with the Kinekt). Simply introduce an Allen key and gently turn clockwise to increase tension, checking as you go.  

Convenience aside, this does away with the need for “lock-out” and similar engineering to overcome unwelcome travel. Vecnum list the unit as self-lubricating, which is arguably another bonus. However, it employs fit and forget bearings, which will ultimately require professional servicing/refurbishment once worn.  


Vencum also recommends applying gripper paste (the stuff typically employed when fitting carbon components) to the fork steerer. Good practice for this genre of stem generally I’m thinking, although I’ve never had any issues with the Kinekt or Redshift Sports TEST & REVIEW REDSHIFT SPORTS SHOCKSTOP SUSPENSION STEM (sevendaycyclist.com) Shock stop Suspension Stems.  


30mm (about 1.18 in) travel is 20mm (about 0.79 in) positive, 10-degree negative, rather akin to a suspension fork. Again, in common with the Kinekt, it’s designed to be progressive and not affect the bike’s geometry. Regardless of bar height, or positioning- whether you ride on the hoods, tops, or drops. It's beautifully machined, extruding that industrial beauty that I’m deeply drawn to. Formative impressions are very favourable but we’re in the honeymoon phase at present. Only time and real-world mileage will tell.  


I’d recently switched the fixed gear winter/trainer’s Cane Creek Thudbuster G4 for its G3 predecessor TESTED: CANE CREEK THUDBUSTER ST SEATPOST (sevendaycyclist.com) when I opted to return to this Pro Turnix Gel saddle, which continues the weight saving without sacrifice narrative. I went for the Peaty’s Bicycle Assembly Grease PEATY'S BICYCLE ASSEMBLY GREASE | cycling-not-racing (sevendaycyclist.com) and took this opportunity to replace the seat post collar boot- made from scrap mtb inner tube.  


I’m deeply endeared to both generations of the Thudbuster ST, but I must admit, I’m not overly keen on the G4’s single-bolt saddle clamp design. Not that I’ve had any real-world issues these past two years or so. However, this seems a curious design for one intended to support riders weighing up to 150kilos.  

 

For those unfamiliar with the Thudbusters, upon hitting a bump these work downward and reward, so force is absorbed at the same rate. This prevents the saddle from bouncing around and robbing rider power. Aside from Mtb and gravel audiences, in my view, they have a lot to offer tandem stokers who don’t always get warning of the lumpier stuff until they’re experiencing it first-hand.  


I also remain a big fan of Redshift Sports Shockstop Suspension Seat post REDSHIFT SHOCKSTOP SUSPENSION SEATPOST | cycling-not-racing (sevendaycyclist.com), although not everyone is sold on the industrial aesthetic and length means its best suited to road biased, rather than semi/compact mtb builds-Ursula being a case in point. There’s not much between them weight-wise either. Something may not be to my tastes but that certainly doesn’t make it inferior, just not the right fit.  I’d noticed some unexpected judder under heavy braking with the new rotor and pads.  


Closer inspection revealed the obvious culprit- a soiled rotor. A simple cure with some Green Oil Clean Chain Degreaser Jelly GREEN OIL CLEAN CHAIN DEGREASER JELLY (sevendaycyclist.com) and some vigorous scrubbing with their Bike Brush. Clean, but not sterile is a rotor’s preferred state. I’d confirmed this by switching back to the SL9 wheel and Swiss Stop Catalyst Pro Disc Rotor  Swiss Stop Catalyst Disc Rotor | cycling-not-racing (sevendaycyclist.com) I’d also discovered a pinch flat and since one thing always leads to another, I’ve switched to Specialized’s Road Sport Tyre and now that roads are getting wetter, I’ve reverted to Motoverde PTFE Chain Lube on the fixed Motoverde PTFE Chain Lube | cycling-not-racing (sevendaycyclist.com) For now, I’ll stay with something dry/waxy to keep Ursula’s drivetrain clean and wear pedestrian. I'll close with Steve's review of the Ravemen LR1200 front light Ravemen LR1200 Front Light | cycling-not-racing (sevendaycyclist.com)
