Check this out! What better way to develop ground-stomping speed for 'cross season? Do the local "Tuesday night Worlds" on your cross bike. Here I am motor-pacing behind a loyal teamate, running a 39 *12/26 (yes a single ring), and running 45 psi in the big 32c Michie's. I even did 90 minutes before and about 30minutes after this thing. I contemplated retirement later that evening :-) Ciao
