A few weeks ago while warming up on the course for a cyclo cross race I cut a turn short and ripped the rear derailer off. That meant game over for the day. While walking back to the start area some guy I didn't know saw my broken bike and offered his BMC mtb for me to use. Really? Wow!!! I got to race after all but got no warmup. The race went off and I stayed towards the back attempting to ramp up my effort as I warmed up. Half way through the second lap "pssssss". I flatted and walked the broken and borrowed bike back to the owner. I went to my car along the way and got $10 for a new tube. This went into and out both sidewalks of the tire.
