After the chamois in two paris of PI shorts had begun to rip out, I decided to take the advice of so many here on the forums and try Performance bib shorts. Because they were on sale, I bought a pair of the Century gel bibs and a pair of the Elite bibs. Though I like the fabric on the PI shorts much better, the performance bibs, at two for about the price of one pair of PI shorts, are extrememly comfortable. I especially like losing the waistband. The chamois in the Elite bibs is as comfortable as the PI chamois. I am still deciding if I like the gel chamois. At first it is comfortable as all get out, but on a long, hot, sweaty ride this weekend it became awfully squirmy at about the 30-mile mark. It did not become uncomfortable, but I think it absorbed enough moisture to endow it with a high "squish quotient" (I'd really rather not think about this any more). I'll decide whether I like it after a few long rides when the temperature isn't pushing 100 degrees F.
