Carbon-Ti X-Rotor Aero Centerlock Disc Brake Rotors | 160/140mm | from 93g

115g (160mm) | Wind tunnel-optimised carbon body | Steel braking track | CenterLock interface

Grade 5 titanium rivets and washers | UCI-compliant rounded CNC edges | Made in Italy

Compatible with 12/15/20mm thru-axle hubs | Not compatible with Campagnolo and Fulcrum AFS systems

The X-Rotor Aero is Carbon-Ti's dedicated aero disc rotor, developed specifically with UAE Team Emirates for time trials and high-speed road racing. Where the SteelCarbon 3 is the all-rounder, the Aero variant takes the same steel braking track and titanium hardware, wraps it in a wind tunnel-optimised carbon body, and targets the niche where rotor aerodynamics actually matter: TT bikes, triathlon, and flat-out road stages.

The CenterLock version uses the same dedicated Al-7075 adapter system developed for the SteelCarbon 3 CenterLock, with a laser-engraved titanium protection plate integrated into the carbon body. It mounts directly without third-party adapters.

Features

Wind Tunnel-Optimised Carbon Body

The carbon spider on the Aero is a complete redesign of the SteelCarbon 3 body, optimised in the wind tunnel for superior air penetration and reduced drag at high speed. 

Steel Braking Track, Shared with SteelCarbon 3

The braking surface uses the same special steel track as the X-Rotor SteelCarbon 3, which means braking performance and heat management are not compromised for the sake of aerodynamics.

Dedicated CenterLock Adapter

The Al-7075 CenterLock adapter integrates directly with the carbon body and includes a laser-engraved titanium protection plate that fits flush into the carbon shape. The low-profile lockring is compatible with 12, 15, and 20mm thru-axle hubs, covering most modern road and TT wheel standards.

Grade 5 Titanium Rivets and Washers

All rivets and washers are Grade 5 titanium, keeping the hardware weight low while maintaining the clamping strength and fatigue resistance required at the braking interface. This is consistent across the entire X-Rotor range.

UCI-Compliant Rounded CNC Edges

The rotor profile features precision CNC-machined rounded edges, compliant with UCI regulations on rotor profiles. This applies to both race-use safety requirements and general rider safety in the event of rotor contact.

Developed with UAE Team Emirates

The X-Rotor Aero was developed to meet the specific requirements of UAE Team Emirates for time trials and high-speed racing, tested by professional riders over months in competition conditions. It is the rotor seen on Colnago TT1 bikes at the highest level of professional cycling.
