I have searched but not found a definitive answer. I want to change my standard 10 speed ultra torque crank for a compact. I have not had any luck in finding a 10 speed. Will an 11 speed crank work with my 10 speed components and chain? I want an answer from someone who has actually run this combination. I can buy a new Record 11 speed crank for what used 10 speed cranks go for on ebay.
