PowerGlide™ II Technology

SRAM's PowerGlide™ II technology is specifically optimised for off-road riding.

Carefully designed tooth profiles and shift ramps help provide smooth and reliable gear changes across the cassette, delivering consistent shifting performance in demanding trail conditions.

Standard HG Freehub Compatibility

One of the biggest advantages of the SRAM PG-1210 is its compatibility with widely used HG splined freehub bodies.

Unlike SRAM Eagle cassettes that require an XD™ driver, the PG-1210 can fit many existing mountain bike wheels equipped with a compatible Shimano HG/SRAM-style freehub body. This makes it a practical option for upgrading a compatible bike to a wide-range Eagle 12-speed drivetrain without necessarily replacing the rear wheel or freehub.

Compatible Cassette Body Types Include:

• Shimano HG / SRAM 8-Speed
• Shimano HG / SRAM 9-Speed
• Shimano HG / SRAM 10-Speed
• Shimano Dynasys 11-Speed Mountain

Please Note: Always confirm your wheel, freehub, and drivetrain compatibility before purchasing.
