E*Thirteen Helix Plus 12S cassette

More Range, Less Weight!

The HELIX PLUS 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.

Features

• Compatible with SRAM™ and Shimano™ 12 speed drivetrains
• Improved shifting performance including Shimano™ 12 Speed compatibility
• Improved interface between steel and aluminum clusters
• E*spec uprated for E-bike use
• 2-piece design allows for replaceable aluminum cogs
• Reduces rear wheel weights, improves braking, suspension function and handling
• Designed to shift with Shimano™ and SRAM™ systems without compromise, so the rider can change components without concern
• E*thirteen’s wider range and 9 tooth cog allows riders to run a 2 tooth smaller chainring for more clearance and reduced weights
• Requires XD™ Driver
• Hope XD drivers are undersized at the clamp location and require a Cassette Shim Kit

Compatibility

• Works flawlessly with Shimano™ and SRAM™ 12s drivetrains, despite the challenges in designing for the different cog spacing and chain behavior.
