Not the OP, but - while 32mm is the manufacturer's spec, there is a perhaps a couple mm more room. The engineering drawing for the fork shows a 40mm radius, and that's what I measure as well. For the frame, I didn't see a similar dimension - I measure 36-37mm (seat stays are at an angle, of course, so also depends how much higher the wider tire sits...).
I don't have anything larger than a 32mm road tire - and that does certainly fit with comfortable clearance.
I wonder if it's possible to squeeze a 700x35 on, if someone has one handy.
