Last year my chain dropped a couple of times on a hilly organized ride and ended up saging back (a first for me). It had dropped before this but we thought the problem was taken care of.

As it turns out it is good thing I did end the ride when I did. There seemed to be a problem/defect with my FSA K-Force 2 piece carbon crankset that came on the bike. In fact, we heard that there have been problems with this crank. My bike is a 2007 Ruby Pro. I switched it to Ultegra and it is working great.
