Product details:

Renthal’s Twinring Rear Sprocket is the longest lasting most durable sprocket you can buy, developed over five years of extensive testing. The Renthal Twinring combines a specially enhanced 7075 T651 aluminum alloy center and an ultra high strength electroless nickel coated steel outer ring. By combining these two materials Renthal has created a rear sprocket that is lighter than steel but more durable than the traditional all aluminum sprockets. The unique flat face design keeps weight to a minimum and prevents fouling on the chain guide. Inner ring is a high strength Ultralight 7075 T651 Aluminum. Outer ring is electroless nickel coated steel for ultimate durability. The outer ring is expanded at 200 °C and then fitted over the inner. This interference fit combined with the wave pattern ensures a permanent bond for the life of the sprocket. The flat socket head screws add additional strength to the sprocket during side impacts. Self cleaning mud grooves between each tooth prevent dirt build up and reduce sprocket wear. Patent pending. Extensively tested by David Knight and Team Honda Off-road.
