The Helix Advantage
The HELIX R 12 Speed Cassette is an upgrade to any SRAM Eagle™drivetrain, with more range than any other cassette on the market. The 9 tooth cog lets you step down onechainring size while keeping the same top end gearing and provides not only better ground clearance, but an overall lighter drivetrain. The aluminum one-piece 42/50 tooth cluster is easilyreplaceable so riders can keep their steel cluster for multiple seasons and freshen up granny as needed without
buying a whole new cassette.
Helix R is also available in a 325g 9-46t
11 speed configuration that’s compatible with both Shimano™ and SRAM™
Drivetrains. Service and Tech Support Unlike SRAM Eagle™, Helix R cassettes have replaceable gear clusters.
That means ongoing service and replacement costs will be less than half that of SRAM™ cassettes. Compatibility
Works flawlessly with Shimano™ and SRAM™ 12s drivetrains despite the challenges in designing for the different cog spacing and chain behavior. Additionally, if your wheel has a SRAM™ XD™ Driver and you want to upgrade to Shimano™ 12s, you not only save money on the cassette, you don’t have to spend the extra on a new hub driver either.
