Had quite a scare today. I was going downhill about 15 mph on my Soma Rush (44:14) when SNAP! I heard the chain break. I felt all kind of awkward chain snagging going on and slowed with my front break to a stop without crashing. I was waiting for the wheel to lock at any minute. I was sure that the chain had got into the spokes and I was going OTB at any moment. Once I stopped, I look down to confirm that my chain was gone. Yep, no chain. I looked back 10-20 yards expecting to see a loose chain on the ground. No chain. I took a closer look at my rear cog and found that the chain has wrapped around the cog! It really scratched the krap out of my frame as well. I had to take the wheel off to remove the chain, which was badly twisted and mangled. I was able to coast home most of the way. Scary! Maybe the chain was loose and came off during a bumpy descent.
