- Ultra-Torque axle: In steel
- The Q Factor remains the same (145.5): The widths and biodynamics of the stroke are the same.
- Unidirectional carbon fibre cranks, steel axle and aluminium chainrings: Good stiffness and optimum power transmission.
- Symmetrical teeth on the internal chainring: Fluid, precise transmission, even with extreme cross-chaining.
- Optimised design for any chainring combination: Maximum performance, whatever the course style.
- Double Fixing: Assembly of the large chainring on to the crank is secured by a ring of 123mm bolts, while the inner chainring is attached to the outer by way of 96mm pcd bolts.
- Surface treatment of the chainrings for longer life
