MTB Cassettes

We designed Helix cassettes because riders deserved more range and fewer compromises.

Up to 578% range from a proprietary 9T cog means you keep climbing gears for the steep stuff and still have something to push on the fire road home. More range than SRAM Eagle. More range than Shimano. And it works with both, plus TRP.

Two-piece serviceable clusters change the math on cassette ownership. Small cogs take the beating. Large cogs coast along. With Helix, you replace the worn part and keep riding the one that isn't. Less money out of your pocket, less waste in the world.

The 9-52T delivers a maximum 578% range for riders who want every gear. The 9-50T tightens steps for snappier shifting. The 11-speed 9-46T keeps legacy drivetrains running with modern range. All on XD drivers with flat-top chain compatibility for smooth, quiet shifts across the full spread.

The Loam Wolf praised Helix Race for "shorter, sharper and smoother shifting performance" with "shifting under load significantly improved." Wideopen Magazine noted it offers range "dwarfing that of SRAM and Shimano's biggest efforts."

Helix Race when performance matters most. Helix Plus and TRS Plus for reliable range at a friendlier price. Everything is backed by a 5-year warranty.
