I could definitely feel my jeans gliding over the pavement, in the knee area.. Wouldn't have done it on my own but I was following another rider, with a few years under her belt after she took a couple of track courses, so it happened without me putting much thought into it.. The scary part is that it was a left-side lean and the left sides of my tires aren't scrubbed nearly as well as the right sides. Never repeated the "feat" lol
