More Range, Less Weight
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.
*Requires XD™ Driver
Works flawlessly with Shimano™ and SRAM™ 12s drivetrains, despite the challenges in designing for the different cog spacing and chain behavior.

2 aluminum cogs, 10 steel cogs. PVD finishing on Intergalactic model is twice as durable.
