- Steel and aluminium composite rear chainwheel.
- 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.
