I was going for a ride early yesterday morning, and about 1 mile into the ride, I shifted to the largest cog, and the chain ended past the cog, in the spokes...no damage done though...I spent a good part of the afternoon adjusting/indexing my derailleurs. Took a walk at the end of the day, felt good.
Got up early again this morning and took the bike out and finished the ride I started yesterday...the time I spent on the derailleurs yesterday was well spent, I had never experienced such a silent and smooth shifting drivetrain before
