2mm id pfte tubing is what i'd use, run it as close as you can to the bosses (so only 3-5mm exposed at each end) should be crush resistant enough with the load distributed over that sort of length!fiendish feet":d5zniqf6 said:Hi i use liner cable bit like the liner used for Klein Internal frame routing
for exposed cables on top tube .
With individual straps i'd probably use something like a short section of outer under the strap.
I'll be doing a bit of offroad bivvying next year due to some pretty major lifestyle changes, so if theres nothing else on, i'll be off.
