A friend has a Canondale touring bike with 28" x 1 3/8" Conti tires. We're overhauling it and want to put in new tubes. In our area we're having a very hard time finding 28" tubes with presta valves, but it seems like a 700Cx28 out to work fine. Has anyone ever used 700C tubes in 28" tires without any problems? Thanks!
