That's okay, few long climbs around here, so I'm sticking with the 12-27 except for the one race I do in March that has a .7 mile 12% climb, and I've got a 12-30 for that. Actually, for the past year I've been mostly using a 12-23 - one tooth progression from 12-19, 21, 23.

110rpm is 36mph in a 50/12.

Thanks, waterrockets. More stuff to think about.
