Gravel Cassettes

Born from our legendary MTB Helix line, our gravel bike cassettes deliver wide-range gearing and buttery shift performance. Compatible with SRAM®, Shimano®, and TRP® drivetrains, they're a true drop-in upgrade that extends your range without compromising shift quality. Whether you're chasing KOMs on fire roads or grinding through all-day mixed terrain, Helix cassettes give you the gears to go further and climb steeper.
