Helix Race 12-speed, 556% range, 384g
More Range, Less Weight
The HELIX Race cassette is an upgrade for any SRAM™ Eagle™ or Shimano™* drivetrain, offering a wider range than any other cassette on the market. The 9-tooth cog allows you to downsize a chainring while maintaining the same top gear ratio, improving not only ground clearance but also the overall weight of the drivetrain.
PRODUCT FEATURES
Compatible with SRAM®, Shimano®, and TRP® shifters and derailleurs with the same number of speeds and similar cage capacity.
The 2-piece design allows for aluminum cog replacement.
Enhanced e*spec version for e-bike use.
BENEFITS
Reduces unsprung weight on the rear wheel for improved suspension function and handling.
Excellent shifting with uncompromising Shimano™ and SRAM™ systems.
The wider gear range and 9-tooth cog of the e*thirteen allow riders to use a 2-tooth smaller chainring for improved ground clearance and reduced weight.
*Requires an XD™ freehub body.
NOTE: Hope XD freehub bodies are undersized at the clamping area and require a cassette spacer kit, which is included in the box with the 9-50T cassette.
