Dependable all-weather gear cables but don't cut corners when fitting them
Weight: 339g Contact: www.fibrax.com
Fibrax Pro-formance Sealed Derailleur Cables are weatherproof and ideally suited to harsh conditions: cyclo cross, winter and mountain bikes the most obvious candidates.
Made here in the UK, the comprehensive kit includes 2.7 metres of frictionless 5.5mm outer casing, clear inner sleeve and two stainless steel inner wires measuring a generous 1.8 and 2.1 metres long. Fibrax also offer a version for tandems and bikes with unusual cable routings.
To finish things off, we've twelve ferrules, two cable end caps and four rubberised cuffs to protect paintwork from unsightly cable-rub. Good preparation is key to getting the best from these systems, so get some proper cable cutters. I was able to use the bike's existing outers as a template but it's worth double checking the new cables against the frame with ferules in situ. Mark cut points using a Stanley knife and cut swiftly – it's hard work.
Remove the ferrules and slip the outers and inner linings through. The inner lining should extend beyond the rear mech by 5mm but in practice this proved tricky. I left everything in situ overnight before trimming and soldering the cable ends.
To be fair, cable stretch was non-existent; both mechs impeccably behaved come the morning and haven't missed a beat over the last few weeks and two hundred plus miles. The Univega's cables, chains and cassettes see the worst weathers. Blasted with torrential rains, mud, silt, and spray on coastal roads, shifting has remained consistently precise.
Even the outers seem relatively kind to paintwork, although the grinding paste of sticky debris was beginning to gnaw through my tourer's lacquer topcoat, prompting swift introduction of those little rubber cuffs.
