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.

Features:

• The inner ring of the unique Renthal Twinring is engineered from Ultralight 7075-T6 aluminium, keeping the weight of the Twinring to a minimum.
• The outer ring features an Electroless Nickel Plated steel, ensuring an ultra long service life and maximising power transfer.
• 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 permanent 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.
• Inner ring is anodized in colours to suit application.
