I find myself in the extreme minority of folks for whom this saddle does NOT work. It came on my Roubaix Comp and having given it about 200 miles, gave up. I attribute it to my own specific anatomy, given the near-instant-icon status of the Power saddle.
I first had it set up with a fairly high positive tilt (+2 deg. I believe). Eventually nudged to 1 deg. then to perfectly level, still not finding the sweet spot. The contact point on the left side of the saddle kept causing my leg and groin area to go numb. I'm also someone that likes to spend long days on big climbs, and like a more traditional long, narrow nose on which to move around some on 15+ mile climbs. I found myself immediately out of runway on the Power saddle.
Based on the remarkable reviews of the saddle I was eager to give it a run, but after 200 miles and 3 trips to my fitter, ended up going to my tried and true Selle Flite.
