CDX Enviolo Fin Line 9-Spline 22t Rear Sprocket

The Gates CDX Enviolo Fin Line 9-spline 22T rear sprocket is a high-durability belt drive cog built for the sustained torque and mileage typical of e-bikes, commuting, and trekking. Its updated Enviolo mounting interface improves security at the hub and helps reduce sprocket noise in rough, wet, or dirty conditions, while the Fin Line center track design keeps the belt tracking correctly when the ride gets messy.

• Threaded retaining ring mount - Improves sprocket retention versus snap-ring style designs and helps minimize noise under adverse conditions

• Aerospace stainless steel construction - Wear-resistant material choice for long service life under high loads
