SteelCarbon Technology — Engineered for Performance

The X-Rotor SteelCarbon 3 combines multiple high-performance materials to achieve an exceptionally lightweight construction while maintaining the strength and reliability required for demanding braking applications.

High-Performance Steel Braking Track

The redesigned 1.8mm-thick steel braking surface is engineered to improve braking performance, promote efficient heat dissipation and encourage more uniform brake pad wear.

Its refined profile delivers consistent contact with the brake pads, supporting dependable braking across a range of riding conditions.

Structural Carbon Fiber Carrier

The carbon fiber inner body significantly reduces overall rotor weight while providing structural support for the steel braking track.

This hybrid construction contributes to the rotor's exceptionally low 68 g weight.

Grade 5 Titanium Hardware

Laser-engraved Grade 5 titanium rivets and washers connect the rotor's components, combining excellent strength, low weight and corrosion resistance.

Together, these materials create a technically advanced braking solution developed for performance-focused cyclists.

Semi-Floating Design. Consistent Braking Performance.

The X-Rotor SteelCarbon 3 features a semi-floating construction designed to accommodate the thermal expansion generated during braking.

This architecture allows controlled movement between the steel braking track and carbon fiber carrier, helping manage thermal stress and support consistent braking performance.

Combined with the redesigned steel track and improved heat dissipation, the rotor is engineered for reliable performance during demanding descents, technical riding and high-speed road cycling.

Precision Engineering. UCI-Compliant Safety.

The third-generation X-Rotor introduces a refined outer profile featuring CNC-machined rounded edges.

This design improves safety and complies with UCI regulations governing disc brake rotor edge profiles.

The result is a rotor that combines advanced performance engineering with the safety requirements of competitive cycling.
