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.
Cyclists can not only get a better performance, but also enjoy fluidity with SPIRIT cranksets.
Right now, SPIRIT has 9 sizes, 140/145/150/155/160/165/167.5/170/172.5 mm to meet cyclists' different demands for shorter crank arms.
With these different sizes, it is more in line with various fitting theories.
Crankset Length is a crucial factor that many cyclists consider. Without proper measurement, choosing the wrong crank arm length can lead to discomfort or even injury. Among the various options available, the 160mm crankset, 165mm crankset, and 170mm crankset are often the most popular choices.
SPIRIT could enable the development of more crankset components and various chainrings, and also provide more types of bikes with the same platform concept in the future.
