Gravel Cassettes

Gravel riders have opinions on gearing, and we respect that. Some want a tight, road-like setup for fast mixed terrain. Others want maximum range for bikepacking missions where walking isn't an option. We built a gravel cassette lineup that covers both ends and everything in between.

The Helix Race 12-Speed 9-45T is our gravel-specific cassette, purpose-built for gravel and XC drivetrains. At 500% range and 330g, it's a direct drop-in replacement for SRAM® XPLR® 10-44T cassettes with 13% more range. Flat-Top chain and XPLR® derailleur compatible, so there’s no need to change your gravel derailleur. Excellent shifting with both Shimano® and SRAM® systems.

Need an even wider range? Our mountain bike cassettes are a great option for riders running a mullet gravel setup, which pairs your drop-bar shifter with a mountain bike derailleur and a wide-range MTB cassette. The 9-50T delivers 556% range. The 9-52T pushes to 578% for riders who never want to walk a climb. Pair one with a smaller chainring and you've got a setup that handles any terrain you point it at.

Off.Road.cc praised the 9-45T for "crisp shifting and low weight" and noted "shifting quality rivals that of SRAM's cassettes." The Radavist called our 9-52T cassette "an even better fit for 1x adventure bikes" than MTB.

Every Helix gravel cassette features our patented two-piece construction. Replace aluminum and steel clusters separately, cutting service costs and reducing waste. Cross-compatible with SRAM®, Shimano®, and TRP® drivetrains, so you're not locked into one ecosystem. XD and XDR driver required.
