E-THIRTEEN Helix Race cassette 12S

The HELIX R 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. - Additionally, if your wheel has a SRAM™ XD™ Driver and you want to upgrade to Shimano™ 12s, you not only save money on the cassette and don’t have to spend the extra on a new hub driver. - All e*thirteen cassettes require XD drivers for mounting - Please reference our hub compatibility article to ensure the e*thirteen cassette will work on the hub you have before purchase. Specifications: Compatibility: - Works flawlessly with Shimano™ and SRAM™ 12s drivetrains*, despite the challenges in designing for the different cog spacing and chain behavior. - Freehub Mount: XD™ and XDR™ Drivers Only - Material: 2 aluminum cogs, 10 steel cogs. PVD finishing on Intergalactic model improves durability and wear life. - Range: 556% - Speeds: 12 Speed - Weight: 375 Grams
