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
