The PG-720 is SRAM's dedicated 7-speed downhill cassette, with a tight 11-25T spread and gear steps SRAM has optimised for gravity riding.

Highlights

  • 7-speed, 11-25T: 11-13-15-17-19-22-25
  • Built for SRAM 1x DH drivetrains
  • Runs on SRAM 11-speed chains
  • Compatible with the SRAM X01 DH drivetrain
  • Fits HG-splined driver bodies
  • Black cog finish

Built for downhill

SRAM designed the PG-720 as part of its 1x DH system, pairing seven closely spaced gears with an 11-speed chain. It suits riders who want a dedicated gravity cassette rather than a wide-range trail one.

Two hub fits

SRAM offers the PG-720 for traditional HG driver bodies and for slim 7-speed DH-specific HG hubs, and notes that the spacer is removed to fit a slim hub. The distributor lists this code as the version for slim hubs, so check your hub before ordering.

Compatibility and fit

Use with an SRAM 11-speed chain and a 1x DH drivetrain such as X01 DH. Install with a cassette lockring tool and a torque wrench, or have our workshop fit it.
