Renthal Ultralight rear sprockets are manufactured to extremely tight tolerances from a special material developed to withstand the rigours of supercross, motocross and enduro racing. The 7075 T6 aluminum alloy rear sprockets are 66% lighter than steel, yet incredibly durable. Their advanced tooth profile, concentrically and accuracy of fit provide maximum power transfer and long-life. Renthal's combination of a very high strength base material and an exceptionally hardwearing surface result in significantly increased sprocket life over other brands.
