1. High strength and light weight: The mountain bike sprocket adopts upgraded solid 7075-T6 aluminum alloy, which is light weight but high strength. 2. Narrow and wide teeth: The narrow and wide teeth design greatly increases the contact area with the chain, so that each tooth can be fully inserted into the chain, increasing the grip, so that you no longer have to worry about the chain falling off, and it is easy to pass through rough roads. 3. Positive and negative advantages of a single disc: remove redundant parts and reduce weight. Easy to clean. Unshifting: Reduces the amount of energy the rider is distracted from shifting, allowing the rider to focus more on the ride. The gear ratio changes are relatively continuous, and the gear ratio can be continuously changed without changing the front and rear gears at the same time. . 4.CNC precision machining: CNC precision machining and anodizing plating keep the medal surface smooth, bright color, non-fading and corrosion-resistant. 5. Compatible with all kinds of 104BCD cranks: This single chainring can be used with all types of 104BCD cranks.
