Helix R Cassette - 11-Speed, 9-46t, Nickel

The HELIX R Cassette is an upgrade to any SRAM Eagle or Shimano drivetrain, with more range than other cassettes on the market. The 9 tooth cog lets you step down one chainring size while keeping the same top end gearing and provides not only better ground clearance, but an overall lighter drivetrain.

• 1 aluminum cogs, 10 steel cogs
• Designed for use with XD and XDR drivers only
