Cube Aerium C:68X SLT 2026 - Road Bike
The Cube Aerium C:68X SLT represents the pinnacle of triathlon and time trial design. Developed in close collaboration with Lucy Charles-Barclay, Cube’s most advanced carbon frame yet has been tested in the wind tunnel and refined in real-world racing conditions. The result is a machine engineered to save watts, maximise efficiency and provide athletes with every competitive advantage.
Key Features:
- C:68X® carbon frame, wind tunnel developed with pro athlete input
- C:68X® carbon aero fork with integrated cable routing
- Shimano Dura-Ace Di2 12-speed drivetrain with power meter
- Shimano Dura-Ace hydraulic disc brakes
- Newmen Streem TT.80 VONOA carbon wheels
- Continental Grand Prix 5000 TT tyres, 28mm
- Integrated hydration and storage options
- Available with 0% APR finance
The C:68X carbon monocoque chassis integrates adaptable storage and hydration systems including the ability to fit up to two hydration systems, keeping fuelled and focused on long stages. The integrated Cube Aerium cockpit system gives you fingertip control and a wide range of adjustment to dial in your optimal aero position.
At its core, the bike runs Shimano’s flagship Dura-Ace Di2 12-speed electronic groupset, delivering seamless shifting and powerful hydraulic braking. A Dura-Ace power meter chainset (54/40T) comes fitted as standard, allowing you to train and race with precision. Riders also have the option to switch to a 1x setup with a cover plate that preserves the bike’s aero lines.
Rolling speed comes from Newmen Streem TT.80 VONOA carbon wheels, paired with Continental Grand Prix 5000 TT tyres for low rolling resistance, grip and aerodynamic advantage. Every watt you put down is transferred efficiently to the road.
Comfort and control are enhanced with a Selle Italia Watt saddle and Cube’s aero carbon seatpost. Every detail has been considered, from hidden cabling and integrated storage to disc brake integration that maintains clean airflow while delivering reliable stopping power.
The Aerium C:68X SLT is more than a bike it’s purpose built for racing against the clock whether you are a triathlete or time-trialist chasing your best performance.
