Cables & Cut Downs







Winter is hard on components and kit. The Univega is the most obvious candidate for some sealed Jagwire road elite sealed brake and shift cables. The existing mid-range inners and budget outers were still in remarkably rude health but generally speaking, I replace control cables seasonally on competition bikes, annually on working bikes.

Impervious designs are nothing new but they’ve come a long way in the last few years.

Housings used to be inflexible builders-hose types, which were difficult to cut and tended to chomp through paintwork with alarming haste, especially when gritty, slimy stuff got trapped between the two. The Gear cable housings proved tough customers to snip, brakes easier than some bog standard benchmarks. 

Though supplied with finish-friendly, rubberised cuffs, Jagwire’s CSX outers are soft, pliable and easily pruned with decent cutters. Same goes for the stainless steel inner wires, which I am told are impregnated with a special polymer lubricant.

Corrosion is something of a moot point but these also feature a non-stick liner, designed to run the cables entire length, theoretically sealing it from grit, dirt and anything else that might impair performance.

Decent snips in hand, everything cuts and comes together beautifully. Stretch is supposedly another moot point. I was surprised to discover some sloppiness at the front lever-easily corrected by pulling the cable taught and snugging down the Avid’s pinch bolt. 

Budget cables by all accounts can lead happy and productive lives but they are prone to fraying and stretch. Traditional MO with these is to pull them taught and leave overnight. Next day, take up the slack, nip everything tight. Flush through with some PTFE based lube every few weeks and in my experience, they’ll plod on for a good six months or so.

The Univega’s rear cable run; though hardly torturous, isn’t the smoothest, high-quality cables make all the difference. Precise, Michael gratifying setup required some patience but rewarded with the slickest action I’ve experienced from the cheap but relatively cheerful cantilevers.

Force of habit usually sees me giving inner wires a quick fortnightly squirt of PTFE based lube but I’ve managed to resist and am exposing the system to wet, greasy roads wherever possible. So far, with zero maintenance, modulation and feel remain superior to mid range cables that I’ve traditionally run, then replaced annually.

Some will argue this level of performance is overkill for a daily driver. I disagree. So long as the groupset, new or old is of a decent calibre, it makes as much sense to have fit n’ forget cables as it does cartridge bearing bottom brackets, pedals, hubs etc.

Come the New Year, I’m going to cut the Univega down to a 1x9. This means I can lose the front mech, save a few grams and put the widely spaced cassette to better use.

Was tempted by a Shimano Zee crankset but having done one of my “January’s a long month, want or need” calculations; I’ve decided to use the existing LX spider. Chain-line is important, so I’ll be installing a shorter UN55 and using the swapping the 32 tooth for the 44. Shorter bolts and Tacx tool in post, it's a job for a quiet January afternoon.

In the meantime, for the budget conscious road fixer fraternity, we have a long term review of System EX track crankset http://www.sevendaycyclist.com/system-ex-crankset. There are better options for track racers wanting to stick with old school square tapers but for the money and winter fixed/single speed projects, it’s superior to some, similarly priced European competition.               

Having left the Univega basted in crap long enough to conclude of Pro Green MX aftershine 101 is a genuinely effective and long-lasting preserve http://www.sevendaycyclist.com/pro-green-mx-triple-pack I’ve been playing with a No quarter bike care kit.

No quarter is also specialist refinishers, offering powder coated and bespoke wet spray makeovers. Therefore, I was expecting something pretty special.  This full ensemble comprises of bike shampoo, assorted sponges, detailing brushes, carnauba hard paste wax and of course, micro-fibre cloths-two in fact.  

Packaging takes its lead from the cosmetics industry and yes, the wax has a really pleasant fragrance.  Unlike traditional bike washes, which are deployed via trigger spray, you pour four capfuls into a bucket of warm water and whip it up into a thick, sudsy lather.

I was quite impressed at that point and though purporting to be kind to ALL surfaces, I wasn’t surprised to discover it’s not the most visually impressive of formulas. That said; it does a decent job of loosening ground in filth-cocktails of slime, spent derv, oil, and road salt, caked on cowpats too. Aside from scent, the wax seems very similar to other hard pastes purporting similar properties.


Fairly economical-a little of both products goes surprisingly far, though overall effect hasn’t been so rich, or glossy as I’d expected. That said; the wax appears to remove some light corrosion and its protective qualities appear pretty good to date...Sleet, snow and similar wet stuff is forecast over the coming weeks, so let’s see how it holds up.
