The crankset is made of aluminum, which is the same material used in aircraft, and has features such as durability, high strength, and resistance to deformation, so it can be used for a long time. The hollow design of the bicycle crankset is designed for weight reduction and does not add extra weight to your bike. It's lightweight and easy to carry. The bicycle crankset has standard precision machining to ensure chain retention, extending its service life and reducing friction and noise. In addition, reducing the weight of the rotating parts leads to more efficient pedaling due to the reduction of inertial weight. The crank arm length of the crankset is 170mm.The crank arm and chainring bolt do not overlap. And it is compatible with many cars and is a good part for repairing cars etc. BCD: 130 mm (suitable for 107-110 mm) Arm length: 170 mm Fit: Pedal diameter = 9/16 Color: Black, Silver Weight: Approx. 555g › More
