Honda Renthal Twinring Rear Sprocket

Renthal's Twinring™ chainwheel is the longest lasting most durable chainwheel you can buy - developed over five years of extensive testing. The Renthal Twinring™ combines a specially enhanced 7075 T6 aluminium alloy centre and an ultra high strength electroless nickel coated steel outer ring.

 

By combining these two materials we have created a chainwheel that is lighter than steel but more durable than the traditional all aluminium chainwheel. The unique flat face design keeps weight to a minimum and prevents fouling on the chain guide.
