The second-generation narrow wide chainring is fully CNC integrally formed. A lot of optimizations have been made on the basis of the first-generation narrow wide chainring, and the functionality has been significantly improved. A sludge drainage groove is added to the tooth root, and the problem of oil sludge accumulation is improved. The design of the long and short teeth is more in line with the actual wear ratio, and it also brings a better effect of preventing chain drop. Compatible with almost all bicycle chains currently on the market. The surface is treated with sand.
