Sixweel CS-XR-1286 12V 11-34T Cassette

The Sixweel CS-XR-1286 12-speed 11-34T cassette is designed to offer a high balance of lightness, strength, precision, and durability, with features also suitable for professional and competitive use.

The cassette belongs to the Sixweel Evo 12-speed range and is the result of a constantly optimized production process, with particular attention to CNC machining and material heat treatments.

Materials and Production Process

Sixweel has continuously optimized the manufacturing process for its Evo 12-speed cassettes, achieving stable and reliable data regarding machining and material heat treatment.

These materials and processes allow for achieving the intended design tolerances and accuracy for the finished product with the highest possible precision.

Machining via CNC hollowing allows for weight reduction while maintaining a strength level suitable for professional competitive use. The resulting structure also helps improve the cassette's durability and reduces the mileage required during the break-in period.

Compared to traditional stamping processes, CNC machining offers greater durability and allows the sprockets to withstand higher torques, a particularly important feature during phases of greater stress on the drivetrain.

Differentiated Materials for Optimal Performance

Sixweel uses different materials in different areas of the cassette, a choice determined through specific calculations and a long period of data collection and analysis.

The goal is to achieve the best possible compromise between:

• Efficiency
• Stability
• Corrosion resistance
• Durability
• Lightness
• Aesthetics

This design allows the Sixweel Evo 12-speed cassette to combine low weight with high strength and long-term reliability.
