Yay! New Wheel Day









A couple of days after dropping the rim and Shutter Precision SD8 hub with Mick Madgett, he’d built the wheel! Much whooping and cheering (to coincide with The KA’s service and MOT pass) followed and I arranged to collect at my earliest, practical opportunity. Not least since I needed to put the hub through its paces.  


No sense spending good money on wheel(s) than skimping on rim tapes and inner tubes either, so I got some fresh Schwalbe and bought in three tubes, but the second Schwalbe Marathon GT365 TESTED: SCHWALBE MARATHON GT 365 TYRES WINTER UPDATE (sevendaycyclist.com) eluded me. Not the lightest by any means but extremely durable and dependable on and off-road. 


I’ve sent the PD8 over to the UK importer so they can organise servicing and once that’s back, I’ll get it built into the White Line rim and it’ll serve as the second/spare front wheel for my fixed gear winter/trainer.  


Now, one of the minor things about the Shutter Precision hubs is that they come sans skewer. Not sure what I’d done with the Shimano quick release, since I had defaulted to the Kryptonite Wheel Boltz security skewers, which though not impenetrable, offer decent defence from casual tea leaves- say when parking up for short periods- bladder, or colon smoothie stop anyone?  


I poached the gold  Halo, since that wheel was doing something close to nothing and I couldn’t find that belonging to the Nexus. I still have a soft spot for the humble commuter hub, it’s just the resistance and specification aren’t of the sort, conducive to the K-Lite lamps, or indeed the 800lumen Exposure unit that preceded them.  


The Nexus in question is a 6V 2.4-watt model. Sanyo and Shimano both produce 1.5-volt units and they’re very affordable, but again, inadequate for my riding needs. Staying with hubs, John Moss did indeed have an Alfine unit, but I’ve metaphorically missed the boat- he'd had a clear out, donated it and his tyre mountain to a cycling charity. Wasn’t meant to be.  

Another time, another place maybe a suitable hub will materialise. For now, I’ll enjoy the a ’la carte mix of Sputnik rim, XT hub, 11-25 cassette and Tiagra rear mech.  


Dynamos aren’t everyone’s bag, nor are they suitable for all contexts. I’m still very interested in powerful, rechargeable units, especially on pared to the essential's road bikes.  


Steve’s been racking up the miles with Sigma’s smaller Buster- the 700, which I also have a fondness for, although primarily as a helmet-mounted companion. The sensible range of modes and high-quality optics also caters for town and suburban work, with enough bite for letting off some steam along semi-rural escapes. SIGMA BUSTER 700 FRONT LIGHT | cycling-not-racing (sevendaycyclist.com) 

Up the rear, I’m still fond of the German marques’ Blaze SIGMA BLAZE REAR LED LIGHT | cycling-not-racing (sevendaycyclist.com) and Infinity SIGMA INFINITY REAR LED LIGHT | cycling-not-racing (sevendaycyclist.com)rear light, which are bright and in the latter context, very frugal, especially for a single, constant mode.   


Trail Distribution has kindly sent me some Bike Medicine Purple Extreme Chain Lube. It’s a synthetic blend, originally conceived for oil rigs and similarly harsh conditions. It's claimed to perform in temperatures between +400-100 degrees Fahrenheit, so the average British winter shouldn’t tax it. In common with some others, you can scoot off but ideally, leave curing overnight. 


Bike Medicine claim it will extend the life of older components, while enhancing the performance of packet fresh drivetrains, without attracting dirt and contaminant. Will be interesting to see how it holds up against some wallet-friendly favourites, including Weldtite TF2 Performance All Weather Lubricant TF2 PERFORMANCE ALL WEATHER LUBRICANT | cycling-not-racing (sevendaycyclist.com)          

There is a school of thought which says dry lubes for spring/summer and wet for winter. Makes sense on some levels and keeps things simple. However, these things are nuanced. I err towards stay put synthetics on daily drivers and working bikes. Price aside, I’m impressed by Muc Off Ludicrous AF and have returned 700miles from a single application. The Peaty’s Link Lube Premium All Weather Chain Lubricant PEATY'S LINK LUBE PREMIUM ALL WEATHER | cycling-not-racing (sevendaycyclist.com) is another decent default, ditto Rock N’ Roll Gold LV ROCK 'N' ROLL GOLD LV CHAIN LUBE | cycling-not-racing (sevendaycyclist.com), which is also incredibly clean running-welcome any time, but especially winter.  


Ursula is the beneficiary for now. The chain is also in surprisingly good shape- at present rate, I’ve probably got 500miles before it’ll need pensioning off. I’ll wait until the Christmas break for the wheel- will likely coincide with other little, mid-point maintenance jobs. Gives me chance to get some spare cables and straddle wires in. Nothing worse than getting immersed only to be thwarted by a frayed/damaged cable, especially when you can’t just nip out and buy a new one.  


Cable-wise, I’ve gone for some Transfil, a brand supplying cabling to the French automotive industry and producing some decent, virtually maintenance-free cable sets. A great option for bikes in hard service. The outers are quite abrasive though, so be sure to apply some helicopter tape where they touch the frame/forks.

Inspect & Pension Off









 I returned from a wet, greasy ride on Ursula and was about to strip and lightly lube the chain with some Peaty’s Link Lube Dry. Something prodded me to whip out the chain checker and it slid into the links .75 is the pensioning off point for 9, 10 and 11 speed units.  

I plucked a Sram from the stash, pruned by a few links and fitted sans magic link, since though I understand the design principle, I much prefer a solid pin. That said; I slipped the residual links and magic link into a re-sealable bag, into the See Sense Handlebar bag SEE SENSE HANDLEBAR BAG | cycling,-but-not-usually-racing (sevendaycyclist.com), just in case.  

Observation suggests 10 speed chains last between 3-4 months. I’d returned 1600miles from the superlight model which is a good bit more than the 1250 typically managed before they hit .75 on the chain checker. I was also astonished by the amount of congealed lube coaxed from the jockey wheels and derailleur cage once I’d removed the worn chain. Particularly since I’d regularly deep cleaned the drivetrain between lube changes and as appropriate, topping up.   


As for the Peaty’s Link Lube Dry, well that’s another water-based, wax prep, intended for spring/summer use, so now is the time to test.  


In common with all waxes, especially those employing water-based carriers, any trace of pre-existing lubricant must be exorcised. It leaves the spout with a celeste hue, so even coverage is easily achieved. Once cured, it assumes a waxy glaze, theoretically meaning it runs cleaner, rather than collecting contaminant and scabbing off.  


Time, miles and climate will reveal its true characteristics and staying prowess. Spotted this Austin, while on our chain checking spin. From a distance, I believed it to be a 2CV based Lomax, prompting a closer look (without drawing unwanted attention, or making the rightful owner nervous) 


Several months down the line, my fixed gear winter/trainer’s aheadset was still very smooth and subsequent inspection confirmed bearings and races were still well protected by the Park PPL-1.  


However, I’d come that far and needed to assess the Peaty’s Assembly Grease on bearing components (since it’s apparently perfectly fine). The boot/headset cosey made from scrap mtb inner tube was also perishing, so due replacement. This also presented an ideal opportunity to clean the KMC chain and feed it some of the Peaty’s Link Lube All Weather Premium. 


Packed with Peaty’s and excess wiped, the headset was buttery smooth. I used the excess to grease the stem and Gusset Headlock threads, since the latter is a sitting duck for wet, gritty stuff.  First outing at 6am the next morning and everything felt bang on. Chain serenely quiet, steering quick and ultra-refined.  


Along the lanes, at 20 mph and banking into a right turn, I feel the tyres lose traction-diesel. Thankfully the fixed transmission, experience and decent rubber meant I was able to regain control, without incident.  Diesel vehicles, those with automatic transmissions in particular, drip unspent fuel under more forceful, or sudden braking. Farm vehicles, coupled with the sudden, more intense rains, flushing spillages from the fields are another possibility.  


I’m never one for compulsion, especially when it comes to helmets, but wear mine pretty much every ride. Every so often, I get a gentler reminder of their benefits. Now and then, even the anti-bacterial pads can turn a bit funky too. Steve’s been testing Oxford Mint Helmet Santiser OXFORD MINT HELMET SANITISER | cycling-not-racing (sevendaycyclist.com) . In a pinch, I’ve given whiffy lids a quick blow-over using anti-bacterial santiser sprays and do, from time to time, take mine in the shower with me. A couple of thousand miles along the line and the Bontrager (model) finally succumbed to a flat. A flint, more accurately. It had burrowed into the casing, commuted by wet, greasy roads and dung. 

 

Hardly a major issue, but unwelcome at any point, especially when the weather was turning slightly stormy. Thankfully, I had two spare tubes and two pumps. CO2 cartridge but no inflator. Unsure how that came about-would've made for a quicker pit-stop. Flint removed, fresh tube and 60psi later, I refitted the wheel and rode the remaining 7 miles back without incident.  


The Peaty’s All-Weather Premium has certainly held its own but transferred very readily to hands and bar tape during said mechanical. Upon my return, I gave the bike a quick sudsy bucket wash, put some additional pressure and a drop of glue into the tyre. This is also an opportunity to check/replenish tube stock, pump and in my case, add the CO2 cartridge/inflator.  On that note, I'll end here with my long term review of the Kenda Kwick Journey KS Plus Tyres KENDA KWICK JOURNEY TYRES | cycling-not-racing (sevendaycyclist.com)
