Just bought some Conti Flows, these are 2.3 light weight jobbies but I have just discovered I only have 2.1 tubes ( a spare 7 or 8 of the buggers to be precise)
There seems to be little choice on the big web sites re 2.3 tubes, can anyone recommend a good light weight 2.3 tube.
Failing that what would happen if I simply used the 2.1 tubes ? Its not as if I am stretching them a big amount and they are rubber after all.
