Renthal Twinring Rear Sprocket

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 200°C and then fitted to inner, creating a permanent bond for the life of the sprocket.

Features:

• Inner Ring: The inner ring of the unique Renthal Twinring is engineered from Ultralight 7075 T6 Aluminium. This keeps the weight of the Twinring to a minimum.
• Outer Ring: Renthal Twinring feature a Electroless Nickel Coated steel. This ensures an ultra long service life of the chainwheel, providing you with maximum power transfer longer than ever.
• Precise Construction: The Outer ring is expanded to 200°C to be fitted to the inner ring. Cooling creates a permenant bond. Flat socket set screws prevent lateral movement between the rings in high velocity impacts.
• Mud Grooves: Twinring feature Renthal's self cleaning mud groove technology between each tooth. This prevents mud build up that traditionally leads to quicker wearing components.
