    Renthal's chainwheels are precision CNC machined to extremely tight tolerances to give the ultimate combination of strength and light weight. The 7075 T6 aluminium alloy rear chainwheels are 66% lighter than steel, yet incredibly durable. Their advanced tooth profile, concentricity and accuracy of fit provide maximum power transfer and long-life. Renthals combination of a very high strength base material and an exceptionally hardwearing surface result in significantly increased chainwheel life.
