Renthal Sprocket Hard Anodised 40T

Renthal hard anodised sprockets are specifically designed for road and road racing applications. They feature all the benefits of Renthal off-road aluminium rear sprockets but with increased longevity from the hard anodised process. Hard anodising is an integral surface coating that significantly increases the hardness and wear resistance of the chainwheel surface.

Renthal hard anodised rear sprockets are precision CNC manufactured to extremely high tolerances. The high strength is especially enhanced by using a 7075 T6 aluminium alloy coated in an ultra-hardwearing finish for extreme mileage. The rear sprockets computer-aided design gives the maximum reduction of unsprung weight at the rear wheel, to give maximum power transfer. The Renthal rear sprockets are 33% lighter than steel and the self-cleaning mud grooves prevent dirt buildup and help keep the sprocket clean.
