The Rinpoch RC3230 Hollowtech Track Crankset is a precision CNC-machined integrated bottom bracket crankset engineered for maximum stiffness and efficient power transfer under aggressive track and fixed-gear sprint loads.
Constructed from AL6061-T6 crank arms and a AL7075-T6 chainring, the RC3230 delivers an ideal balance of low weight and structural rigidity for both velodrome racing and street fixed-gear riding. A 30mm hollow spindle enhances torsional stiffness, while the 144 BCD spider supports a wide range of track chainring options.
With a 42.5mm chainline and narrow 140mm Q-factor, this crankset promotes efficient pedaling dynamics and direct torque response—perfect for riders demanding precision and reliability.
