X-Rotor SteelCarbon 3 X-AFS Disc Rotor

A disc rotor isn't just there to stop the bike — it has to do it predictably, descent after descent, even as heat builds and trust in the braking system becomes everything. The X-Rotor SteelCarbon 3 X-AFS is built for exactly that, drawing on technology proven at World Tour level and engineered specifically for Campagnolo and Fulcrum wheels using the X-AFS standard.

The hybrid construction is the core of the design: a carbon fiber body cuts rotating mass without giving up stiffness, while the special steel braking track delivers powerful, consistent, and easily modulated braking even under the harshest conditions — a semi-floating layout built to manage heat exactly where it matters.

Designed and 100% manufactured in Italy, every detail reflects craftsmanship that goes beyond looks: the CNC-machined rounded edges fully comply with the latest UCI regulations, making this rotor a natural choice for professional racing as much as for serious competitive riders.

Key benefits:

• Hybrid technology: semi-floating construction with a carbon fiber core and steel braking surface for superior thermal management
• Premium materials: Grade 5 titanium rivets and locking ring
• X-AFS optimization: full compatibility with Campagnolo and Fulcrum X-AFS systems
• UCI compliant: rounded edge profile for racing safety
• Italian craftsmanship: meticulous build quality with no shortcuts

This isn't a showpiece component — it's built for the latest possible braking point, done safely. You'll find it in our Rotors collection, alongside the rest of our X-AFS compatible range.
