Maybe the shoes, I don't know. Now, I tried two different sets of toe clips, and ended up with chaffing around the toenails, and one big blood blister on the left, bit toe that didn't go away for two weeks after I switched to Power Grips. Anyway, that was my biggest improvement to the bike, and not because they're pretty. They aren't.

Everyone tells me clipless is better, but it's usually important for me to ride in office shoes. Changing back and forth just wouldn't work for me.
