I've ridden for years and I've never had this happen, but my chain doubled over and got caught in the front derailour. I had just started shifting down from the high front gear when it happend. The ride is basically new, so what if anything do I need to do to prevent this from happening again?:biggrin:

I've seen this happen and the cause was the jockey pulley on the RD being too close to the large sprocket. As the pulley momentarily touched the sprocket the chain doubled at the
FD cage and jammed. Adjusting the "B" screw and moving the pulley away from the sprockets cured the problem.
