Part #11 on the Drivetrain Diagram
The 54 Tooth Rear Sprocket includes the 9 holes that are compatible with our standard Sprocket Clamp Assembly. A larger rear sprocket helps increase your performance and acceleration for large hills or hilly terrains for any motorized bicycle.
Note: Only compatible with the 415 Heavy Duty Chain
Other than drilling holes in it to match my bolt pattern, it works great. 54 tooth sprocket is perfect match for a 230 lbs. guy around town on gas bicycle. Started out with 36 tooth, way to small.
Good climbing gear
