SimpleCycle ~ Ah yes, I forgot to mention that. Indeed, I am wearing padded bike shorts. Not the overly expensive kind. I've read about the shorts in the forums also, and am looking at getting a less expensive pair of Perl Izumi (sp?). But I remember reading a post that said, one should be able to ride 20 min without needing a pair of bike shorts.... Maybe my backside just isn't broken-in yet.
