if you are fitted to the bike properly and the saddle is hurting, you need a different saddle. But even the best saddle will hurt if the seat is too high, or too far forward, etc, etc.

so. Make sure you're fit properly to the bike. Next question. WHERE is it hurting?

you should feel the pressure on your sitbones. if that's where it's hurting (and not inside of there on delicate tissues) you might consider a different saddle.
if other parts (not sitbones ) are hurting, it's either fit or you need another saddle. I hope that makes sense.

ps takes me about 5 minutes to figure out if a saddle is going to work.. lots of experience!
