The original saddle on my Norco--some regulation standard--was quickly obvious on my longer day trips--+30km--to be unacceptable--sore sit bones--even with bike shorts on. I then switched to a simple terri--and did a long 80km ride--same problem--sore sit bones after 30km...went with a WTB--the idea being it was flat and rigid--however--for my regular work rides and such-under 12km--without bike shorts--absolutely useless. Even With bike shorts--the cut out--just didn't feel right. I have just installed a specialized--and so far-so good, past 20km anyway.
