The HELIX R 12 Speed 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.

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. As an added bonus, Helix R 12s clusters are backward compatible with and can be used to upgrade your existing TRS+ 9-50 cassette.
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.
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. And it is 60g lighter.
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. The aluminum one-piece 42/50 tooth cluster is easily replaceable so riders can keep their steel cluster for multiple seasons and freshen up granny as needed without buying a whole new cassette. The new Intergalactic PVD finishing is twice as durable as anodized models.
This is only the first 9 cogs 9-36 and the rear cluster is purchased seperatly and is also available from the Feel Good Bicycles online store.
