Inner ring is the same high strength Ultralighta?? 7075 T651 aluminumused for the standard Renthal sprocket
Outer ring is electroless nickel coated steel for ultimate durability andis 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. Thisinterference fit combined with the wave pattern ensures a permanentbond for the life of the chainwheel
The flat socket head screws add additional strength to the chainwheelduring 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 muchlighter than an all steel rear sprocket
