SunRace's catalogue lists the CSMX8 EA1 11–51T at 587g, while other manufacturer-linked listings for the metallic-silver configuration report approximately 512g. This appears to reflect different MX8/MX80 production specifications, so the exact weight should be confirmed against the packaging/part number when ordering.
Performance
The 51T largest sprocket gives riders a significantly easier climbing gear than a conventional 11–42T or 11–46T cassette. The 11T smallest sprocket retains useful high-speed gearing for descents and faster sections.
The 11–51T progression is:
11-13-15-18-21-24-28-33-39-45-51T
Compatibility
This cassette uses a standard Shimano HG MTB freehub interface, so it is not designed for SRAM XD or SRAM XD-compatible freehub bodies. It is intended for compatible 11-speed MTB drivetrains and derailleurs capable of handling a 51T largest sprocket.
