Thanks for your input--it was especially helpful since you've tried both the Lithia and the Jett. I'm doing progressively longer rides on the weekend...a 48 two weeks ago, 67 last week...with a few 20-30 milers thrown in during the week. Today I only rode 31 miles but my butt was so sore afterward that I ended my ride short. I'm determined to do this century (and another hillier one in Nov.) ...perhaps I need a more heavily padded short?
