More Range, Less Weight The HELIX Race Cassette is an upgrade to any SRAM™ or Shimano™ 11speed drivetrain, with more range than other cassettes 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.
PRODUCT FEATURES
Compatible with SRAM™ and Shimano™ 11 speed drivetrains
2-piece design allows for replaceable aluminum cogs
RIDER BENEFITS
Reduces un-sprung rear wheel weight for improved suspension function and handling
Excellent shifting with Shimano™ and SRAM™ systems without compromise
e*thirteen’s wider range and 9 tooth cog allows riders to run a 2 tooth smaller chainring for more clearance and reduced weights
Extend the life of 11-speed components by adding gear range to an existing bike
*Hope XD drivers are undersized at the clamp location and require a Cassette Shim Kit.
no, thank you
