The Helix Plus 12-Speed 9-50T cassettes are a drivetrain upgrade on a budget for analog and e-bikes alike. Engineered to deliver Helix shifting precision, and cross compatibility with all SRAM and Shimano 12-speed drivetrains, the Helix Plus is also e*spec rated to withstand the rigors of e-MTB. e*thirteen's exclusive 9 tooth highest gear cog, provides a 556% gear range, and lets you step down one chainring size, while keeping the same top end gearing, meaning both better ground clearance and an overall lighter drivetrain. It features: 

  • 12 speed 9-50t -  9,11,13,15,17,20,23,27,31,36,42,50
  • Compatible with XD driver freehub
  • Offering a 556% range utilizing an XD driver to enable a 9-50t, 12sp cassette
  • Weight: 410g
  • Special note for Hope hub owners: Hope XD drivers do not adhere to the XD specification and require an additional shim. Shims can be acquired from E*Thirteen
