The HELIX R Cassette is an upgrade to any SRAM Eagle or Shimano™ drivetrain*, with more range than any other cassette 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. Add some color to your bike with their copper, nickle gray, gray, blue, purple, or orange option.
