Renthal Twinring Rear Sprocket - 49 Tooth - Silver 1540-520-49Gpsi

• 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 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
