Season:2025

Brand:Cube

Code:831200fogGRY

The Cube Aerium C:68X Race Triathlon Bike is fast, aerodynamic, and delivers race-proven performance.

Designed in collaboration with World Champion Lucy Charles-Barclay, the Cube Aerium C:68X Race Triathlon Bike is engineered to be the fastest triathlon frame ever created by Cube. With cutting-edge aero design, integrated hydration and storage systems, and disc brake integration, this bike offers maximum speed and performance in every race. Tested in wind tunnels and on race courses, the Aerium C:68X is the ultimate tool for triathletes aiming for top-tier results.


C:68X Carbon Fibre Technology: The C:68X® carbon frame blends high-performance fibres and nano-particle-infused resin to create an incredibly light, strong, and stiff structure. The Precision Advanced Twin Mould manufacturing ensures precise carbon fibre placement, eliminating the need for bonded sleeves or inserts, and setting a new standard in bike frame technology.


Optimised for Speed: Aerodynamically refined with aero fork design and Twin Head Tube technology, the Aerium C:68X reduces air resistance, allowing for higher speeds. The unique twin tube profile enhances steering stability in crosswinds, reducing buffeting for better control.


Aero Optimised Geometry: Developed through wind tunnel testing and Computer Fluid Dynamics (CFD), this frame geometry is stable, agile, and fast, ensuring optimal performance across a variety of race conditions. The Aerium C:68X is built for high-speed, endurance, and performance.


Full Internal Cable Routing: Say goodbye to external cables cluttering your setup. The Aerium C:68X features a clean internal cable routing system, ensuring a neater, more aerodynamic design while reducing cable damage and maintenance.


Hydration System 2.0: With configurable hydration systems like the bar-mounted hydration unit and frame-integrated bladder, the Aerium C:68X lets you stay hydrated without disrupting your aero position. The extra bladder compartment above the bottom bracket provides added volume for extended races.


Storage System: Keep your energy gels and bars easily accessible with the modular storage system that doesn’t interrupt your aero tuck. The Aerium C:68X offers a fully aero-enclosed compartment for food, spares, and tools, maximising efficiency during long-distance events.


Advanced Twin Mould Technology: Cube's Advanced Twin Mould process uses two precisely engineered moulds for a stronger, lighter frame with optimised carbon fiber density. This ensures a durable structure designed to withstand the rigors of race day while maintaining lightweight performance.


Configurable Cockpit System: With wide range adjustments for comfort, endurance, and performance, the Aerium C:68X Cockpit system is fully customisable. Choose between Low or High setups, adjust arm pads, and modify the saddle stack and reach for the best riding position tailored to your needs.


Shimano Dura-Ace Di2 & Ultegra Gearset: Experience seamless shifting with Shimano Dura-Ace Di2 electronic shifting paired with Ultegra chainsets and derailleurs. Enjoy perfect gear ratios at your fingertips for any terrain.


Dura-Ace Di2 Hydraulic Disc Brakes: The Dura-Ace Di2 hydraulic disc brakes give you the power to brake later and harder, enabling you to maintain speed and control throughout your race.


Newmen Streem Aero/Sprint TT Wheels: These high-performance wheels, combined with Continental Grand Prix 5000 TT tyres, provide exceptional speed, stability, and aerodynamics, getting every watt of your power directly to the road.
