Features:
1. Using high-strength aluminum alloy, reduce weight, improve strength and rigidity, strong force, not easy to break
2. The positive and negative teeth help manage the skewed chain and prevent the chain from falling off.
3. All the connecting positions of the positive and negative teeth are in a circular arc transition, and sediment accumulation is rejected
4. Vacuum electroplating, anti-oxidation, vacuum electroplating forms a special protective film to prevent surface oxidation
5. CNC precision processing, high hardness, wear resistance and durability
