More Range, Less Weight The HELIX Race Cassette is an upgrade to any SRAM™ Eagle™ or Shimano™ drivetrain*, with more range than any other cassette 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®, Shimano®, and TRP® Shifters and Derailleurs of the same gearing count and similar cage capacity
The 2-piece design allows for replaceable aluminum cogs
E*spec uprated for E-bike use
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 allow riders to run a 2-tooth smaller chainring for more clearance and reduced weights
*XD™ driver required.
Hope XD drivers are undersized at the clamp location and require a Cassette Shim Kit that is included with the 9-50T cassette in the box.
Compatibility
