The chainringadopts an extended tooth shape, so even if the chain jumpsviolently, it is difficult to get out of the teeth,so as to prevent the chain from falling off. Our tooth heightis 8.5mm.The spacebetween teeth is much larger than the chain.When you jump wildly, the chain will jumpviolently and it is difficult to get out of thespace between teeth. This will trulyprevent the chain from falling off Manuf
