SR4 Chain Ring
(Single Ring 4 Arm)

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 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.
