currently have 1 1/8 tires on a 451 rim. they don't take the potholes nearly as well as my 1 1/2 tires did on the 406 rim, but I've switched.
i see a 1.35 primo comet kevlar belt (same tire I have in thinner) on bikefriday, but it is lower psi. i'm a big guy so would like higher psi.
anything else out there?
