Aluminum Alloy Crank: The crank is made of high strength aluminum alloy, which is and does not break when stepped on.
Good Features: The bike crankset has a stable structure, good compression resistance, thickened aluminum material, and is sturdy and durable.
CNC Machining: Precise CNC machining improves strength and rigidity, and the is and without burrs.
Lightweight Design: The left and right cranks are hollowed out in a large area, which greatly reduces the weight while maintaining the strength.
Threaded Central Axle: High strength aluminum alloy, low noise, improved rigidity, and the sealing system is not easy to be damaged.
