Description
Renthal - 12100239 - Twinring™ Rear Sprocket - 51 Tooth - Silver - Yamaha
Features
- 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 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 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
