Rear inner tube
Front inner tube spares are easy but finding a rear inner tube is not proving so easy.
Anyone in the UK managed to source or even look for one yet?
Continental ones are advertised on internet but there are non available, even through Continental directly.
A Heidenau one is available in a 4.5 x 18 size that lists 150/70 18 as a correct fitting but I can't find one from a more mainstream manufacturer.
I don't need one but I like to have spares just in case, especially of an odd sized one.
