Twinring® Rear Chainwheels

The longest lasting most durable off-road sprocket you can buy developed over 5 years.

The unique flat face design keeps weight to a minimum and means the TwinRing’s as narrow as a regular chainwheel.

Inner Ring is high strength Ultralight 7075 T6 Aluminium. Outer Ring is Electroless Nickel Coated steel

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