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

The Sixweel CS-XR-1286 12-speed 11-34T cassette is a solution designed to offer a high balance of lightness, strength, precision, and durability, with characteristics 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 heat treatment of materials.

Materials and Production Process

Sixweel has continuously optimized the processing of Evo 12-speed cassettes, obtaining stable and reliable data related to machining and heat treatment of materials.

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

Machining using CNC hollowing allows for weight reduction while maintaining an adequate level of strength for professional competitive use. The resulting structure also helps to improve the cassette's durability and reduce 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 characteristic particularly important 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 defined 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 reliability over time.
