Today was my first fall (and this is also my first posting on this forum). I was riding in a pace line at around 20mph. My front tire hit the back tire of the bike in front, and I went down hard on the asphalt. I've got road rash to the entire left side of my body, and banged up my knee a little. Funny, I never even thought about whether or not I would un-clip in a fall until I read the previous postings on this thread. At some point during the fall, I came un-clipped, so that wasn't a problem. I did some research on bike sites about what to use on road rash to promote healing without scarring. Found a great product -- Johnson & Johnson Advanced Healing Adhesive Pads. Everyone should stock up before their next fall.
