Description
Cube AERIUM C:68X SLX Aero TT/Triathlon Bike 2026
The Cube Aerium C:68X SLX Aero TT Bike is modelled on triathlete Lucy Charles-Barclay’s World Championship-winning machine, built for uncompromising speed and endurance. Designed with configurable hydration and storage options hidden behind aero hatches, it allows riders to run up to two integrated hydration systems, making it an ideal choice for long-distance racing where self-sufficiency is key.
Cube Aerium C:68X Aerodynamics and Components
Equipped with a Newmen Streem Aero/Sprint TT 60/80 Vonoa wheelset fitted with Continental Grand Prix 5000 TT tyres and aero valves, the bike delivers rapid acceleration, aerodynamic efficiency, and reliable grip through corners. The Cube C:68X cockpit system offers a wide range of aero bar adjustments, ensuring every rider can achieve an optimal aerodynamic position.
Cube Aerium Drivetrain and Power
A SRAM Force AXS 2x12 drivetrain provides precise electronic shifting, while the built-in power meter ensures riders can accurately monitor and manage effort. This combination delivers smooth, reliable performance in demanding race conditions.
Cube Frame and Design
Crafted from Cube’s premium C:68X carbon, the Aerium C:68X SLX is the fastest frame Cube has ever produced. Developed in close collaboration with Lucy Charles-Barclay, the frame features an aero fork, disc brake integration, and in-frame hydration and storage systems. Wind tunnel tested and proven in competition, it represents the pinnacle of Cube’s aerodynamic innovation.
