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 features also suitable for professional and competitive use.

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

Materials and production process

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

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

Machining using CNC hollowing allows for weight reduction while maintaining a level of strength suitable for professional competition 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 characteristic during periods of greater transmission stress.

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 long-term reliability.
