I'm curious about the CAUSE and the EFFECT. Which was it: A. Did the derailer just separate into two parts on its own? Then the broken off part got caught in the spokes, causing you to lurch to a stop?
Cause: Derailer fell apart on its own Effect: Broken bits fell into the wheel B. Did your derailer get caught in the spokes while you were riding? Your wheel ripped the derailer in two and you lurched to a stop Cause: Spokes grabbed derailer Effect: Bike lurched to a stop and the wheel broke the derailer C. Could something else have gotten into your rear wheel, like a stick? Cause: Stick in the spokes grabbed the derailer. Effect: Bike lurched to a stop and the stick broke the derailer Getting the rear der caught in the spokes is not uncommon. The result is usually a busted derailer and often a badly bent derailer tab. Derailers randomly commiting suicide by exlpoding themselves into two parts while JRA (just riding along) is not common.
