Crankset Hollow Crankset CNC Process Crank Length 175mm Aluminum Alloy Crankset

  
Anodizing process: The surface is anodized, which is wear-resistant and scratch-resistant, effectively protects the metal surface and is easy to fade. CNC process adopts CNC technology, high-precision milling, high strength and uniform force. The positive and negative tooth discs are designed with positive and negative wide and narrow tooth shapes to reduce chain wear, strong bite force, not easy to drop the chain, and efficient transmission. The high-strength aluminum alloy crank is made of 6061 aluminum alloy, and the disc is made of stainless steel. It has high strength, light weight, impact resistance, anti-corrosion and anti-rust.

Material: Aluminum alloy crank + stainless steel disc. Number of teeth: 32 teeth.
