Performance
The 10–50T spread gives plenty of climbing range for steep off-road terrain without sacrificing the smaller 10T high-speed sprocket. The large 50T sprocket provides a low climbing gear, while the 32–50T sprockets use CNC-machined A7075 aluminium construction to help keep overall cassette weight down.
Compatibility
The MZX1 is designed for SRAM XD driver bodies and is intended for SRAM-compatible 12-speed MTB drivetrains. It is not a Shimano HG cassette, so the rear hub must have an XD-compatible driver.
Best Suited For
- Cross-country MTB
- Trail riding
- Enduro
- Steep and technical terrain
- 1x12 SRAM-compatible drivetrains
- Riders wanting a wide gear range with relatively low cassette weight
