I've just fitted a set of 32mm to my wheels, I wanted 28 but was restricted by rim width too.
Read horror stories of fitting them, how you need a spare 3 hours and the strength of a bear. Being only 8 stone soaking wet I priced up a fitting with the LBS. But when they turned up I had a go. Both done within an hour. Hybrid not built up yet, but hoping to try them out this week. I'm looking forward to stress free miles.
