Renthal Twinring Rear Sprocket

Highlights

• Inner ring is the same high strength Ultralight 7075 T-6 aluminum used for the standard Renthal sprocket.
• Outer ring is electro-less nickel coated steel for ultimate durability and is designed with the minimum amount of material to keep weight down.
• The outer ring is expanded at 200C and then fitted over the inner; this interference fit combined with the wave pattern ensures a permanent bond for the life of the chainwheel.
• The flat socket head screws add additional strength to the chainwheel during side impacts and eliminates contact with the chain guide.
• Self cleaning mud grooves between each tooth prevent dirt build upand reduce chainwheel wear and weight.
• Will outlast a standard all aluminum sprocket by 3 times, yet is much lighter than an all steel rear sprocket.
