Rethal Rear Sprockets (Ultralight)

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 aluminium alloy rear sprockets are 66% lighter than steel, yet incredibly durable. Their advanced tooth profile, concentricity 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 sproket life over other brands.
