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.
Compatibility: Works flawlessly with Shimano and SRAM 11s 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 and dont have to spend the extra on a new hub driver.
Freehub Mount: XD and XDR Drivers Only
Material: 1 aluminum cogs, 10 steel cogs. PVD finishing on Intergalactic model is twice as durable.
