Well, Rick really stole my thunder with the whole hip thing. Now, my tailbone incident seems quite silly, really. Anyway, a new harder seat was put on the bike a few weeks ago with no change in fit. It seemed better, but I got my first real test last weekend when I did a 3+ hour ride with some steep climbs. My sit bones were a little tender when I returned, but the tailbone was just fine. Yay! Phew! No more inflatable donut for me!
