Renthal Rear Sprocket Twinring SX+F 90-HVA 14- 50t GPSI

A long lasting durable off-road sprocket developed over 5 years.

The unique flat face design keeps weight to a minimum and means the Twinring rear chainwheel is as narrow as a standard chainwheel.

Outer is expanded at 200C and then fitted to inner, creating a permanent bond for the life of the sprocket.
