The perfect balance of weight, strength and durability

ProTaper Race Spec (RS) Front Sprockets are CNC machined and internally broached to precise tolerances from case-hardened, core-refined chromoly steel.

Computer engineering ensures precise fitment, optimal weight savings, and perfect balance. The result is minimal chain drag, maximum horsepower, and uncompromising strength.

A proprietary coating further reduces wear and corrosion, yielding a front sprocket unparalleled in the market.
