Renthal Off-Road Rear chain wheels are manufactured from a specially enhanced 7075 T6 aluminium alloy produced especially for chain wheels.
This particular alloy has excellent wear resistance along with a very high tensile Chain wheel feature:
Precision CNC machining for unequalled accuracy of fit, tooth profile and concentricity. A weight saving design with maximum strength.
The aluminium, at one-third the weight of steel, means the power required to accelerate and brake is decreased, resulting in an improved race performance.
Self-cleaning mud groves -in between each tooth. A silver etched finish resists dirt build up. Select number of teeth below.
Minimum weight at maximum power. Used by professionals.
