Cheers for the info….like the idea of checking front mech….so just had a look at the bike spec on this site and its there clear as mud 31.8 so i guess its the same….just want to get a q release one for it as she is off to the Alps with me next summer, nothing too mad just a load of cross country etc but even some of that can get a little hairy going down hill so wanna be able to drop the seat a little easily……cheers again from the UK
