Cube AERIUM C:68X SLT Aero TT/Triathlon Bike 2026

The Cube Aerium C:68X SLT Aero TT Bike is engineered to cut through the air with uncompromising efficiency. Building on Cube’s medal-winning race platform, it is equipped with wind-cheating components that maximise forward propulsion and minimise drag. Designed in close collaboration with World Champion Lucy Charles-Barclay, this bike represents the fastest frame Cube has ever created.

Cube Aerium Aerodynamics and Components

Profile Design ASC Pro extensions combine with the Cube cockpit to position the rider in the most aerodynamic tuck possible. The Newmen Streem Aero/Disc TT80/Disc Vonoa wheelset, fitted with Schwalbe Pro One Aero tyres, pairs a carbon disc rear with a deep-section front to deliver maximum aero efficiency. SRAM S-900 Aero brakes complete the package, ensuring powerful and aerodynamic stopping performance.

Aerium Drivetrain and Power

The Aerium C:68X SLT is powered by SRAM Red AXS 1x12 gearing, complemented by a SRAM Red crank with an integrated power meter and a Ceramicspeed waxed Red chain. Every component is designed to transfer rider power into speed with minimal loss, ensuring efficiency from pedal to pavement.

Cube Aerium Frame and Design

Developed alongside Lucy Charles-Barclay, the Aerium C:68X has been tested extensively in the wind tunnel and in race conditions. The aero fork, disc brake integration, and in-frame hydration and storage systems are optimised for seamless performance. Every detail has been fine-tuned to offer zero compromise, giving riders confidence in both speed and functionality.
