I have just got a set of Vittoria 25c road tyres that I have fitted to a set of Campy Eurus 2-way fit wheels. On the flats, the setup works perfectly. As soon as i stand up to sprint or climb, the tyre rubs on the frame just behind the rear brake caliper. It has got to a point now where I have reverted back to a 23c rear tyre. Anybody else have any experience with this? I have read that the frame accepts 25c tyres so just wondering what might be causing this issue.
