Bike Derailler Explosion

Monday - Jul 2 - Biking 52 km

Went mountain biking with Rob. We rode out to Bruce pit, then across to Bell, then on towards Kanata to loop through to Shirley's Bay. At about the furthest point we could possibly be from home, Rob's rear derailler exploded in a bunch of broken pieces and twisted metal. He transformed his bike into a single speed and then limped off for a few km to catch a bus back. I continued on to Shirley's Bay and slalomed around a bunch of Army cadets running around in the woods.
