These Fibrax Spiral Frame Protectors – you get six in a packet, not one – fit around cable outers or hydraulic hoses to stop them rubbing away paint... or metal... or carbon. For the money, they do a decent job.
The don't completely eliminate rubbing. Your bike's cables or hoses still connect, but encased in these soft silicone spirals they don't saw back and forth in the same way. I fitted a couple to the gear cable outers of one of my road bikes, just where they pass the head tube. They're much neater than the short foam tubes that were fitted to these cable outers before, and there's been no visible paintwork damage since.
The front of the bike is where these protectors will probably find most use, because turning the handlebar moves cables/hoses back and forth and there has to be a fair amount of slack here, but the spirals will fit anywhere there's a couple of inches of cable outer. They go on really easily: you just wrap them around from the side, bit by bit, with no need to disconnect the cable/hose.
The alternative to covering the cables like this is to protect the frame from them with helicopter tape. I prefer Fibrax's solution because it deals with the problem at source. You don't have to work out where the cables could connect the frame and then cut out and fit a sticky see-through polygon to match that; you just need to cover the cable wherever it might connect.
Before investing in these, it's worth checking if you can route your bike's cables/hoses in such a way that they can't rub; cable-ties might help. If that's not feasible, these little protectors are a good answer. They can also be used to reduce the noise of a cable outer knocking against a frame or other cable outer.
They're available in black, white, or red. I reckon black spirals on black outers looks best, but barber's pole contrasts are an option if that's your thing.
A simple and cheap way to reduce frame rub from cables and hoses
