Before the Leaves Fall










 August is but a memory now, the mornings have been progressively cooler, and indeed, the sun struggles to wake before 5.30. Perfect opportunities for testing lights, base layers, and other, seasonally appropriate stuff but a reminder that the Holdsworth and Teenage Dream will soon be entering seasonal hibernation.  

Talking of which, for the time being, I’ve mounted the Hutchinson Challenger up front on the Holdsworth and Fixed Gear Winter/Trainer. Thinking behind this was to see how well they roll, handle, etc., and given 1,000 miles (about 1609.34 km) or so, I’d switch them to the rear. Mounting to both rims was very straightforward, requiring a single (admittedly long) composite lever 


I’ve fitted ours to the Halo White Line Classic HALO CLASSIC RIM & SHUTTER PRECISION DYNOHUB DISC WHEEL BUILD (sevendaycyclist.com), leaving the Halo White Line Evaura/ SL9 HALO EVURA & SHUTTER PRECISION SL9 DYNOHUB BUILD (sevendaycyclist.com) shod with the Maxxis. I also opted to switch the Evaura/PD8 to a quick-release Tiagra skewer for added convenience 


Aside from the obvious reasons, I’m keen to see whether they retain their reliability/puncture resistance as the miles rack up. I also took this opportunity to switch the gold anodised Halo Hex skewer for a Shimano Tiagra quick release, for added convenience. A quick bead of grease on the Cro-moly skewer and trough they went. I digress... Tyres. While switching tyres is arguably perfectly acceptable practice, it should only be front to rear, not the other way round.  


All things being equal, a rear tyre is under much greater loading, this will wear faster. Pop it up front after any mileage and you may pay an undignified and potentially painful price. For 67tpi casings, I’ve been pleasantly surprised by how well the Challenger accelerate and their relative compliance 


They’ve also corned very reliably following some episodic heavy rains-even at 100psi, which is quite a bit higher than the Maxxis Refuse, which run at a very modest 50-75psi. However, I wasn’t completely surprised to find the Challenger succumbed to a flint induced flat- it had lodged in some gloop and worked into the casing and put a pinprick in the tube. Just shy of the seam, so easy to patch.   


I’d also spotted some self-extracting crank bolts going for the proverbial song, so bought two sets. One for the fixed Gear winter/Trainer’s Genetic Tibia GENETIC TIBIA TRACK CRANKS & RING | cycling-not-racing (sevendaycyclist.com) and the Teenage Dream’s new carbon cranks.  


Not that I’m whipping square taper cranks off that frequently these days, but the convenience is welcome. Rude not to at £2 apiece, too. These are a European marque, not a Chinese pattern. The latter are something of a lottery. Too much for my tastes-I’ve had some beautifully made bargains and absolute bin fodder.  My pin spanner also appears to have gone AWOL, so I’ve chosen to regrease and refit the existing crank bolts, while I hunt it down.   


On this occasion, I’m using up the Muc-Off Bio Grease TESTED : MUC-OFF BIO GREASE (sevendaycyclist.com) which is a surprisingly stoical blend that performs well across the board. Headsets, hubs, and pedals are its best customers. No issues with metal contact points and fasteners, although Peaty’s Bicycle Assembly Grease PEATY'S BICYCLE ASSEMBLY GREASE | cycling-not-racing (sevendaycyclist.com) has the edge hereNot so long ago I bought a couple of spare 28.6 collars, since these are the sort of thing that fail infrequently (especially if you’re setting stuff up with a torque wrench).  


However, should they fail, it's always at the least convenient time. Aside from doing the important job of holding your saddle up and post rock steady, they’re dead space. Some brands obviously recognised this and began offering models with integrated carrier mounts.  

Now aside from being a point to attach carrier arms, this could include saddle bag supports, lighting, and other nickknacks. I’ve decided to go this route with Ursula, being my four seasons’ beast of burdenI also spotted some pre-cut 106 link 10 spd KMC chains at a similarly keen price, so snapped them up while the opportunity presented. 106 links...Well, I may have pruned Ursula’s just a fraction too precisely.

Magnetic attractions












So, having discovered a traditional cage was going to be a non-starter, even a side entry model, I rummaged through one of my recently reorganised fasteners drawers and reclaiming the Fidlock mount. Thinking their smaller bottle might be in order, though.   


Then of course, there’s the Free Parable Gorilla Cage, which can be mounted on a variety of places around the frame-including the fork blades (stanctions if you are running suspension) via the Gorillia grip, if you don’t have bosses. https://www.sevendaycyclist.com/free-parable-gorilla-clip-and-cage Though better suited to light, bulky items, such as a biviI’ve hauled 1.2 kilos of hobby sized Argon/Co2 welding gas bottle.  


Pretty much the top end of the composite’s carrying capacity but impressive nonetheless, especially given it’s a good bight lighter than the 1.5 PET cage types, including the venerable BBB Fuel tank https://www.sevendaycyclist.com/bbb-fuel-tank-xl-bottle-cage. These are super convenient for touring, gravel and everyday riding, since you can slot in those impulsive rest stop purchases, or indeed a favourite tipple en route home, without consuming valuable luggage space. 


I’ve been impressed by the enduring qualities of the True Tension Tungsten All Weather Lube. Aside from cleanliness, it's tenacious and durable, especially compared with other waxy formulas. Damp conditions and puddles haven’t taxed it, but heavier rainfall and waterlogged roads will eventually lick the lion’s share, requiring a quick top-up. Zefal Bio Degreaser was employed for stripping duties and this too seems quite capable-at least by stock standards.  


True, an aerosol-based solvent spray will blast a scabby chain and cassette clean, piranha fashion. The bio degreaser needs agitating with a brush to stimulate this process, but aside from being more economical, its kinder to surfaces and can be blended (200ml product 800ml water) to make an effective bike wash.  


Concentrates are arguably better choices for workshop duties, or if you’ve a big fleet of bikes but as “off the shelf” formulas go, it seems to strike a decent balance between stripping prowess, without doing nasty things to finishes, seals and other rubberised components. That said; I’ve always rinsed thoroughly with clean water.  


I’ve switched to the Tru Tension Bannaslip Tungsten Wet Lube on the Univega and have the fixed to Muc-Off Wet Weather Ceramic Lube. Its described as a “Propriety ceramic formulation containing integral Boron Nitride compounds in wet and harsh conditions.  


They also recommend it for the higher torque loads of an e-bike, so should be a good option for a fixed drivetrain too.  Will be interesting to see how much, real-world difference the Tru Tension’s Tungsten component makes (or otherwise) long-term to chain life and performance.   

 

This also presented the ideal opportunity to adjust the chain tension slightly. Kenda Kwick Roller tyres are still swift and dependable, which is reassuring, although the only potential weak spot is the 5mm thick belt. This only covers the centre strip, not bead to bead, so hedge clipping season will be the real test... 


I’ve replaced the CR2032 cell in the Cat-Eye Quick computer sensor, with a quick lick of Vaseline. Premium grade cells are reckoned to last over 6,000miles. I’ll be very surprised if the pound shop special manages half that, but head unit and sensor are chatting away just fine for now and the Giles Berthoud Soulor saddle just continues to get better, week upon week.  

I won’t be feeding the hide at least until September’s close. Giles Berthoud recommends applying their food every six months. I’ve deviated from the script during the moulding phase but will adhere to this guidance now onward. 


I’ll end this entry with my long-term review of Passport Crochet Back Cycling Mitts https://www.sevendaycyclist.com/two-year-report-passport-cycling-mi
