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.

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.
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.
Each Twinring® that leaves Renthal's engineering facilities in the UK is individually CNC machined to the tightest possible tolerances, ensuring an accurate and reliable fit.
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.
Twinring® feature Renthal's self cleaning mud groove technology between each tooth. This prevents mud build up that traditionally leads to quicker wearing components.
