E-Thirteen Helix Race Cassette - 12-Speed 9-52t Naranja

e*thirteen Helix Race Cassette - 12-Speed 9-52t Naranja. Engineered for riders who demand precision and versatility, the e*thirteen Helix Race 12-speed 9-52t cassette offers an exceptional 578% gear range, setting a new benchmark in drivetrain performance. The innovative design features a proprietary 9-tooth smallest cog paired with a 52-tooth largest cog, allowing the use of smaller chainrings. This results in improved clearance, reduced system weight, and a lower bailout gear ratio without sacrificing high gear efficiency.

• Seamlessly compatible with Shimano, SRAM, and TRP 12-speed drivetrains, ensuring broad usability
• Patented two-part construction delivers unmatched strength, stiffness, and lightweight performance while simplifying maintenance
• Aluminum and steel clusters can be replaced independently, minimizing service costs and downtime
• The 9-tooth high gear enables smaller chainrings, enhancing clearance and saving weight for a more agile ride
• Compatible exclusively with XD™ and XDR™ drivers (Note: Hope XD drivers require a separate Cassette Shim Kit due to undersized clamp location)
• Extensively tested for both analog and e-bike applications, guaranteeing durability and reliability under all conditions
