I want to buy an innertube to sleeve a small chain (to stop it damaging paintwork) so looked at Halfrauds and can't work out the sizing as they seem to offer 1.90" - 2.1" etc. or 38-45C how do I work out which one has the narrowest cross section?
Wheel diameter doesn't matter as I only want to cut about 18" out of it.
Cheers.
