My first clipless fall was on an mtb. I'd had the pedals for the entire summer and really had not had issues. Then in early July we rode over the Divide from Rollinsville and down in to Winter Park, taking some sweet single track and flying into town. Sure enough, we pulled up to one of the two stop lights in town and, as we wait for a group of young women to cross in front of us, I sloooowly ...fell.....over. Ended up laying under the bike still clipped in.
