Introducing the Renthal Twinring™ Rear Sprocket in a sleek black finish with 49 teeth. This sprocket features an Ultralight™ 7075 T-6 aluminum inner ring for maximum strength, while the outer ring is made of electro-less nickel coated steel for ultimate durability.
The outer ring is designed with the minimum amount of material to keep weight down, and is expanded at 200°C before being fitted over the inner ring for a permanent bond that will last the life of the chainwheel.
The Renthal Twinring™ Rear Sprocket also includes flat socket head screws that add additional strength during side impacts and eliminate contact with the chain guide. Self-cleaning mud grooves between each tooth prevent dirt build-up and reduce chainwheel wear and weight.
This sprocket will outlast a standard all-aluminum sprocket by three times, yet is much lighter than an all-steel rear sprocket. Upgrade your bike's performance with the Renthal Twinring™ Rear Sprocket today.
