Everyone falls! I even did a slow motion fall last week!(and i have been riding clipped in for a few years now and spend around 15 hours a week on my bike). SO dont worry just keep riding:-) And yes, my right knee has tons of road rash on it and I got laughed at quite well by my fellow riders! (I am known for being a bit clumsy- the joke is that I ride so much because once I am on my own 2 feet I will trip and fall!)
