Product Features
Using 7075-T6 aluminum alloy combined with 3D CNC technology, a balance between lightweight and high rigidity is achieved
Equipped with professional chain retention technology, it can provide excellent chain stabilization even under bumpy road conditions
The specially designed positive and negative tooth profiles ensure smoother transmission and effectively reduce noise and wear
The direct-mount design boasts a simpler structure, allowing for quick disc replacement via a dedicated locking ring
Kind Reminder
This product is a direct-mounted disc, excluding the crank and lock ring
Confirmation of specification: Applicable only to SHIMANO direct-mount specification cranks
Recommendation: Regularly inspect the wear condition of the chain to maintain optimal transmission performance
