Ride three today and the seat I bought (a discontinued Bontrager) works fine.

New question. Although the trails I've sought are for the most part concrete and asphalt there are stretches of compacted gravel. It's crushed granite and the edges of the stones are razor sharp. My 90psi 32mm tires are all over the place they're so firm. Any idea (anyone) how wide a tire I can go with to lessen the pressure and widen the track? Even the seams in the asphalt are painful to go over. Still I'm really enjoying myself. This trail is tree covered and the temperature was in the low 80s..what grand time!
