if you´ve got the disc version of the F600, you could squeeze in 650B wheels, a 2" tire should just about fit, if not too knobby...I've ended up with and F600 in blue.
It was all going so well until i found out size large is 18" not 19". I have long-ish legs so the seatpost is truly on the limit.
it weould be some sort of a cheat, but it could make the race easier in terms of braking and rolling resistance...
