I got a bike today with a Concor saddle that has the upward tilt at the rear of the saddle. I recall these were popular for a couple of years, supposedly providing more power for pedaling. Leather is very dry and coming unglued on one side. Looks like buffalo hide. Rust on rails too. So, not a great saddle, but a great price at $15 shipped if someone likes these saddles. I also have a standard smooth black leather Concor for $20 shipped too. Lou Deeter, Orlando FL
