The design of positive and negative teeth makes it unnecessary to install chain guides or worry about dropping the chain, suitable for AM/XC models to modify single discs, recommended for those who like lightweight! The weight can be reduced by about 1KG! (Remove the front dial + left finger dial + large center disc piece + some of the cable management, etc.)

The 30T 27.5" 29er off-roaders are very anxious when encountering dangerous steep slopes due to the large wheel diameter. The same reasoning as flywheel, flywheel is now more and more tend to be the largest gear 40T 42T or even bigger, which can reduce the gear ratio and is more suitable for climbing and cross-country racing.
