More Range, Less Weight

The HELIX Race Cassette is an upgrade to any SRAM Eagle or Shimano shifter and derailluer combination*, 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 (Mounts on an XD driver only)
• 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*thirteens 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 aCassette Shim Kit that is included with the 9-50T cassette in the box.
