How does a gatorskin roll vs a tire without the sidewall protection?
Also, I know I can't run 32mm cyclocross tires on a rim which is about 22mm dia, but how important is it to get just the right diameter, as in 21 vs 22 vs 23?
Also, do you plug the spoke holes in a double wall rim, or is the base tape of a tubular tire carcass strong enough to prevent the tire shearing into the hole?
