Helix R 12s 13-52T Cassettes are a new close-ratio gearing design, engineered specifically to optimize cadence and shift performance under load in steep terrain with frequent climbs and gravity-powered descents. While the close-ratio concept was conceived as a game changer for e-bikes and built exceptionally strong, it's equally at home on mountain bikes and weighs in at an impressive 467g. Offering unparalleled cross-compatibility with all Shimano, Sram, and TRP 12 drivetrains, it features e*thirteen's patented 2pc construction for ease of assembly and service.

Feature:

  • Close ratio gearing cassette for optimized cadence and improved shifting under load
  • Lower fatigue and extended range (Bio or Battery) with sweet spot cadence for max efficiency
  • Helix R 13-15-17-19-22-25-28-32-36-40-45-52 vs Eagle™ 10-12-14-16-18-21-24-28-32-38-44-52
  • Cross-compatibility with Shimano, SRAM, and TRP drivetrains and chains
  • Aluminum and Steel clusters can be replaced separately to reduce service cost
  • Patented two-piece aluminum/steel construction for strength, stiffness, light weight, and durability
  • Optimize cadence and shifts under loads in steep terrain, with a Helix R 13-52T close ratio gearing cassette upgrade for your e-bike or MTB.
