Precision 50 Tooth: The mini bike rear sprocket adopts a precise 50 tooth design, which optimizes torque distribution and creates a smoother gear curve. This reduces friction during transmission, extends the chain's lifespan, and enhances overall efficiency.
Missing chain link size: each chain link size is 20 x 6.6 x 7 mm; The bike chain link is 20 mm in length, 6.6 mm in width and 7 mm in height; The missing link model: CL566R. Compatibility: because 9 speed chain of bike width is 6.6 mm, so this missing link chain is compatible to all 9 speed chain.
