Renthal 437-520-38 Rear Chainwheel 38 Teeth (1857.38)

£32.65

Features:

  • Ultimate combination of strength and lightness
  • Enhanced 7075 T651 aluminium alloy
  • 33% lighter than steel sprockets

Renthal off-road rear chainwheels 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. Minimum weight at maximum power. Used by professionals.
