Depends on the riding position of the bike its on. I have 3 road type bikes and one hybrid. The 3 road bikes run the gamut from a true classic 77 Schwinn Volare with pretty tight geometry and a Schwinn Continental and a 2006 Raleigh Cadent which is a more relaxed geometry frame. I have B-17's on all but the hybrid which is equipped with a WTB something or other. I like the WTB but when I ride that bike I feel like I'm stuck to the saddle. Not in a bad way but just different than the Brooks equipped bikes. I have my bikes set up with a more upright riding position because of various neck and back issues. This position is where the B-17 seems to feel the best. All 3 have been pretty comfy from the get go but the one I ride the most on the Volare is the best of the lots cause its getting conformed to my butt. I never had any more numbness or real discomfort issues with the Brooks than I did with any other saddle but they sure did feel hard the first few rides. Hey they aren't for everybody and thats why we have so many differrent saddles to choose from. Can't we all agree on that?
