Speed rewards attention to detail.
The X-Rotor Aero 140 Center Lock was developed for riders who understand that performance is often found in the margins. Created in collaboration with UAE Team Emirates, it combines aerodynamic efficiency, lightweight construction and reliable braking performance in a rotor designed for modern race bikes.
 
Derived from the acclaimed X-Rotor SteelCarbon 3 platform, the Aero introduces a redesigned carbon fibre structure developed to improve airflow and reduce aerodynamic drag. Optimised through wind tunnel testing, the rotor contributes to a cleaner airflow around the wheel while maintaining the braking consistency expected from a premium racing component.
 
The stainless steel braking track delivers predictable stopping power and effective heat management, while Grade 5 titanium hardware, a dedicated AL7075 Center Lock adapter and laser-engraved titanium protection plate complete a remarkably refined assembly.
Built for speed.
Engineered for control.

What It's For
Riders building an uncompromising road bike where every component has been selected with purpose.
Ideal for race bikes, lightweight climbing builds and aero-focused custom projects where reducing drag matters just as much as reducing weight.
Not every gain is obvious.
Some are simply faster.
