Strange you should mention that - I seem to remember hearing that in the 70s I think in maybe Sheffield some bike mag/fanzine used to feature models tied in old tubes. Then times changed and this was considered unacceptable. Did I imagine this or is there any truth in it?must admit if the other half allowed bike things in the house we could use them as bondage straps.......... but until then dream on !
I went for a scenic sunny ride with @Calum a couple of years ago and all was lovely until he suddenly started getting puncture after puncture. It turned out that his wheel didn't have proper rim tape, just adhesive insulating tape which was falling apart. He spent over an hour trying to improvise rim tape patches out of old crisp packets etc. before finally giving up and catching the train home.I've bodged up improvised rim tape using old tubes. Works fine and it's not a million miles away from its original use.
I wouldn't use them as anything other than emergency tape because a tube weighs a lot more than a proper tape and isn't designed to do the job. I would treat it as a get-you-home bodge so I'd put the minimum pressure in that I thought I could get away with (say 80 PSI or so), not go crazy on fast descents (just in case) and I'd replace with new rim tape ASAP.What sort of pressure will tubes take as rim tape?
I can't give an exact answer but the rim tape's job is to smooth out the chamber of air and cover up the sharp spoky bits. I don't think I took it over about 60psi but I reckon it would safely have taken a higher pressure.What sort of pressure will tubes take as rim tape?
