The SPIRIT modular bike crankset offers a fully customizable design, allowing cyclists to select crank arms, axles, spiders, and chainrings separately.
This modular bike crankset is ideal for those seeking shorter crank arms, which are often hard to find in the market—especially for women, climbing cyclists, and triathletes.
Made from AL-7075-T6 aluminum alloy with full CNC machining, the SPIRIT bike crankset provides an excellent balance of strength and performance, allowing cyclists to pedal efficiently and with greater fluidity.
