With an e*thirteen Helix cassette and a SRAM™ crank, you can now run Helix SRAM™ direct mount rings. Designed to function equally well with SRAM™ and Shimano™ chains, this ring brings insane amounts of CNC detail as well as being offered in anodized colors to match our cassettes as a system. Our exclusive 9T cassette is best enjoyed with a 2T smaller front ring to get the full benefit of less chain and more clearance and range for the same gearing at the top and even lower at the bottom.

• SRAM™ Mount design for compatibility with SRAM™ cranks
• Forged AL7050-T7 for strength and wear resistance
• Compatible with SRAM™ and Shimano™ 12 Speed chains and drivetrains
• Extensive CNC machining for lighter weight and looks to kill
