The Hope T-Rex Ratio Expander Sprocket is designed to increase cassette range for riders who want lower gearing on steep climbs. By adding a 40T sprocket, it delivers easier climbing while keeping your existing drivetrain setup largely unchanged.

Precision-machined by Hope, the T-Rex sprocket offers accurate shifting and long-term durability. It suits SRAM-compatible drivetrains commonly used on MTB and trail bikes and works well for riders upgrading to a wide-range setup without moving to a full groupset change.
