Takes me a little time, whenever I put a saddle on a bike, to get the tilt and forward/aft position just right. I ride both on and off road, and can't think of a saddle that would suit both. The Terry Butterfly that was prev. mentioned might do, but have never tried one. But even if I found one that worked for both, still don't think I'd be happy switching back and forth, and getting adjustment just right. May not be cheaper, but so much easier just to have a dedicated saddle to each bike.
