Forced Hand AKA the Chain Again...












Upon reflection, Ursula had been trying to tell me something. There had been a periodic click, which I had initially attributed to a cleat not being fully engaged, or the rear mech’s barrel adjuster needing a quick tweak. However, the sudden increased loading on a climb saw it implode irreparably. Not something spare links would solve, so a 7-mile saunter home, which gave plenty of scope for reflection.  


Mercifully, I didn’t have to be anywhere until early afternoon, so that took some immediate pressure off. Upon my return, I nipped in for some warmth and to find one of the spare KMC I’d squirreled away. One transpired not to be what I’d requested but I still had a ready cut (106 links) electroplated model, so on it went- using the Magic Link joining system. Not something I’m a major fan of, but it didn’t give me any hassle on this very chilly morning, so we’ll see how it fares.  


Next thing I knew, A gooey mess was lining and coating some tools and other “to hand” essentials in a storage box, so I brewed up a bath of Citrus degreaser with warm water. Gave everything a good tickling with a medium-stiff brush-including the box itself, before rinsing and drying. This time, I lined the base with a bin bag to subvert another gooey encounter. Maybe fate was intervening with my best interests in mind... 


Staying with cleaning, Madison sent me this Finish Line Brush Set, which looks cracking value for money. Time and lots of seasonal scrubbing will confirm, one way or the other. They also sent me their Road Race Superlight Men’s Waterproof Softshell Jacket. A lightweight water and windproof model that packs super small (to the size of a 500ml (about 16.91 oz) water bottle), yet in theory offers decent protection from the elements. 


Letting imagination and fingers wander, I found myself contemplating long cage mechs and 11-32 cassettes for Ursula.  


Thankfully, the voice of reason and serviceable bank balances piped up. This was not the best use of my resources. Double checking confirmed the short cage Tiagra mech will manage 28 teeth- apparently, that’s with a road double, so according to my addled reasoning, a 32-tooth 1x10 mtb setup should be just fine. Measured in inches, rather than “gain” this will give me 74.9 and 29.4 high/low, respectively. More punch when descending, and more grunt when climbing.  


With this in mind, I found an 11-28 tooth Microshift cassette with an electroplated finish for £10 and would introduce that, once the existing KMC X10.73 needed retiring. One thing led to another, and I found myself reflecting on spare wheels. I had stripped a Deore hub from a dead rim nearly two years previously and reckoned it would “come in handy”. 

 

I’d decided it was time to build a decent spare rear wheel for the old girl- ready for duty when the XT/ Rigida Sputnik build wanted some truing and/or general maintenance. 26-inch (559) hoops are still readily available, but I wanted something suitably durable, but without the heft of its bombproof Andra40 cousin. A 32-hole Ryde Zac 19 came under my radar and less than £20. I’m very fond of Araya and Mavic rims but I’m not prepared to pay fancy prices for them, let alone anything with a “vintage” tag.  


Enter stripping, inspecting, and rebuilding the Deore with new bearings and the Juice Lubes Bearing Juice. 18 ¼ balls are what’s needed here, and I bought genuine Shimano. Given their price, there's absolutely no sense in going for anything lower rent, or indeed, opening the hub and re-using the existing balls.  


Dismantling these cup and cone hubs is remarkably simple and requires a couple of basic tools. In this instance, a 15mm cone wrench and a 17mm for the locknut, some stocky waterproof grease.  


The Deore opened with reassuring ease and the grease was closer to an oily gravy, but still offering some protection/lubrication. No pitting, or corrosion in the balls but as I said; better to replace them. I blitzed any residual grease with Green Oil Agent Apple Extreme Immersion Degreaser TESTED: GREE OIL AGENT APPLE EXTREME IMMERSION DEGREASER (sevendaycyclist.com), then rinsed with fresh water.  


Dried thoroughly, I packed the hubs with Juice Lubes Bearing Juice and then added 9 fresh balls each side. Being a seriously tenacious synthetic, they hold the balls super securely- I was able to switch to the freehub side without fear of them falling out.  


A little extra grease on the bearings (for improved protection) and axle, I slid the latter through the freehub side, adjusted the cones so a tiny amount of play presented before holding the cone secure and winding the locknut home. Satisfyingly smooth once more.  


As tends to happen, no sooner had I done that, then this Halo Spin Doctor arrived. Sealed bearings this time and reckoned to be closer to the Shimano XT, it’s a more obvious choice for a brand new build/ One I’ve left in the extremely capable hands of Mick Madgett.

Pre-Hibernation Tweaks










 

I’ve been settling to some little jobs before Holdsworth, and Teenage Dream enter seasonal hibernation. I’ve decided to revise the Holdsworth’s stem spacer height and replace the budget expander wedge. I’ve also decided to switch the Teenage Dream’s rear tyre. While I love the Vee Tire Co Rain Runner infinity’s speed, they seem slightly susceptible to punctures, so I had a rummage in the rafters, hoping to find these Schwalbe Lugano TESTED: SHWALBE LUGANO ROAD CYCLING TYRES (sevendaycyclist.com)   


A little portlier and erring more towards commuting and winter training, but given my preference for dawn blasts, some additional reliability is welcome. Instead, I found a solitary 25mm Freedom Thick Slick (which the Holdsworth is shod with), so popped that on the rear. I would’ve preferred a matching set but aesthetic pedantry aside, some would argue this is another example of personalisation and for now, I’ll stick with that!   


I’m still researching potential replacement(s) for the Schwalbe Marathon Mondial Dual Defense, which have done 7,000miles and still going strong, although starting to show some formative signs of wear. There is a school of thought recommending alternating front and rear tyres for longevity.  


I can see the merits on paper. In practice this is a dubious practice-whipping a partially worn rear up front is inviting a very nasty face-plant on a wet, greasy ride. I will often switch the part worn front to the rear, to get my money’s worth, but then, a brand spanking new tyre goes up front! 


No sooner had I switched Ursula’s chain to the Peaty’s Link Lube Dry PEATYS LINK LUBE DRY CHAIN LUBE | cycling-not-racing (sevendaycyclist.com) this Muc Off Ludicrous AF arrived in the post. Claimed to be the world fastest lube brewed for road, mtb and triathletes, it promises to perform in temperatures as low as minus 20, and extend chain life, so it will be interesting to see how the next few months pan out.  Typical of high-end lubes, chains need to be surgically clean before applying and Muc-Off recommends leaving it a full 24hours curing. 

 

One thing led to another (as it invariably does, with me) and before you know it, I’d whipped Ursula on the work stand, out came the rear wheel. Shifting had been slightly off again and I suspected this was down to the cassette's lockring working slightly loose. Snugged tight with trusty cassette tool, I also suspected, the microshift bar con needed to be dialed fractionally tighter- a slight, clockwise turn of my 4mm Allen key-sorted. Out came the sudsy bucket and sponge and the old girl was gleaming again.  


Chain, ring and cassette exorcised with solvent, I drizzled Muc-Off Ludicrus AF into the links. The Teenage Dream’s drivetrain received identical treatment, coinciding with the tyre swap and a review of the wedge pack. Dead CO2 cartridge was consigned to the bin and given the Uk’s present shortage of said gas, it might be a while before I acquire some more... I’ve also been witnessing extensive panic buying of fuel.  


Traffic backed up along the streets, reminiscent of the last fuel shortage, during the summer of 2000. In the corner of London where I was living, some people were actively trying to scale the tankers. On one occasion, I had two 20 litre MOD jerry cans full of leaded fuel for motorcycles (older Japanese machines, though designed for unleaded, had no problems with the more toxic blend).  


People were begging me to sell them it (some more aggressively than others). Leaded petrol is ruinous to catalytic converters, as several hapless people discovered, having filled their late-model Toyotas.  Whether the UK will assume a state of compulsory rationing, last experienced in the early 1970s remains to be seen.    

  

Back on two wheels, I’ve been pleasantly surprised by the Sigma Infinity Rear LED Light SIGMA INFINITY REAR LED LIGHT | cycling-not-racing (sevendaycyclist.com) it’s compact, bright and simple, with favourable run and charge times.  Those looking for a super potent rechargeable front light may like to take a look at The Ravemen PR2400 https://www.sevendaycyclist.com/ravemen-pr2400-front-light
