Lady in a car crowds me, I catch the edge of a newly poured concrete driveway, with a very sharp broom finish. If fall over kind of like you do when you goof on a trackstand and can't get out of your clips....with the addtion for forward movement.

Observed result shredded bike shorts. abrasion from right cheek to knee. right side of my selle turbo saddle trashed.

best i can do for you
