Fibrax Pro-formance Sealed Derailleur Cable Kit

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.

Verdict

Dependable all-weather gear cables but don't cut corners when fitting them.

Hi, I've seen two references to stretch in cables here recently but hadn't heard of it before. What stretches? Does the outer shrink?

Also could you describe what makes these cables weatherproof? Is there some sort of rubber seal integral with the ferrules?

thanks

Cable stretch only affects the inner wires but wasn't an issue here. Generally speaking, I leave budget cables overnight and retension them come the morning.

As for the housings, these are particularly stout affairs employing a clear sleeve locking out dirt, grime and ingress right to the mechs.

As you say,popping some silicone grease in the ferrules at the point of installation, coupled with subsequent, periodic squirts of PTFE spray greatly improves longevity and performance of cheaper gear/brake cables.

How do they compare technically to the gore ones? They have a clear plastic section over the bottom bracket which ends up getting mashed. this defeats the object.

Technically they are exactly the same, the only difference is on the Gore there has a very flexy v-brake boot type item that finishes of the system.
As the review says, the kit is built burly which means you need a good set of cutters to get through the outer.

Just as an aside, inner sheaths are available separately.
Plus they're made in Wales. Save the British Economy.
