Patterson Crank Won't Shift

I always keep my Patterson crank in the larger gear and start out in 1st for each ride. Today it seemed like I was getting no resistance. I found out the Patterson crank had slipped into the lower gear and would not go back up to the larger gear. Does anyone know if there is a specific adjustment or do I need to take it to the dealer to be worked on? If so, I will also have a larger sprocket installed. I need a broader range of gears.



  • not much to go wrong with a patterson - cable stretch if you have any slack in the default sector position where cable attaches to crankset.
