Lab-Tested Structural Integrity & Torsion Resistance

The central bracket configuration of the 6-Ultra G2 has been repeatedly refined and validated through advanced Finite Element Analysis (FEA) simulations to eliminate any vulnerability under heavy loads.

In machine-driven test cells, the design successfully mastered 10,000 torsion fatigue cycles at a demanding 80–120 Nm rating. Ultimate failure lab testing proved that its peak destruction threshold hits an incredible 283 Nm to 284 Nm—representing a massive 45% improvement in structural integrity over the previous generation design.

Redesigned Friction Interface & Thermal Stability

The braking surface undergoes multiple precision heat-treatment cycles to enhance surface hardness, mechanical strength, and heat rejection. The friction path has been completely redesigned to deliver a 30% larger pad contact area than its predecessor.

Capable of managing extreme temperatures up to 500°C without warping or experiencing severe fade, this rotor provides dependable, linear deceleration even under the heavy kinetic energy generated by stopping a 100 kg rider mass from 60 km/h to zero in 5 seconds flat.

Real-Road Calibration & Maintenance Guidelines

To minimise rotor rub and ensure exceptionally quiet performance, the runout tolerances are tightly managed via automated flattening machinery backed by manual calibration. The final production spec has been heavily verified through extensive over-the-road testing by more than 10 professional field testers and racing riders.

• Pad Recommendation: For elite-level, noise-free performance and consistent bite characteristics, high-performance metal brake pads (such as Shimano L04C) are highly recommended.

• Safety Wear Limits: To ensure safe operation, always verify that the disc thickness stays safely above 1.4 mm, and that the brake pad compound measures above 0.5 mm.
