The chainring adopts an elongated tooth shapewhich makes it difficult for the chain to escape from the teetheven ifit jumps violently, thus ensuring that the chain does notfall off
• Our tooth height achieved 8.5 mm, Increased tooth height improves chain retention 
• Manufactured using 7075-T651 highly durable aluminum alloy
