The CUBE Aerium C:68X SLT Triathlon Bike is engineered for absolute speed.
Designed in partnership with World Champion Lucy Charles-Barclay, the CUBE Aerium C:68X SLT is the ultimate triathlon time trial bike, meticulously engineered for elite performance. Every component, from the aerodynamic carbon frame to the integrated hydration and storage systems, has been refined through wind tunnel testing and race-proven feedback to give you an unbeatable advantage on the course.
Aerodynamically Optimised Carbon Frame - C:68X® Technology
The Aerium C:68X SLT uses CUBE’s premium C:68X® carbon fibre, combining high-modulus fibres with nano-particle resin for unmatched stiffness, reduced weight, and maximum strength. Manufactured using Advanced Twin Mould construction, this frame delivers professional-level performance with zero compromises.
Fully Integrated Aero Cockpit & Internal Cable Routing
Every watt counts. The Aerium cockpit system offers extensive adjustability for stack height, armpad width, and saddle position to help you dial in the perfect aero tuck. Internally routed cables maintain the bike’s clean lines and reduce drag while also cutting down on maintenance.
Dual Modular Hydration System 2.0
The fully integrated hydration system includes a bar-mounted bottle for on-the-go sips and an optional internal bladder housed above the bottom bracket. Stay hydrated without ever leaving your aero position, ideal for long-course triathlons or Ironman races.
Built-In Storage System
Stay fuelled without slowing down. The modular frame-integrated storage compartment keeps nutrition gels and bars within easy reach. Additional lower compartments can hold tools, CO2 cartridges, or spare tubes, neatly and aerodynamically.
Twin Head Tube Design
Distinctive and functional, the Twin Head Tube reduces air resistance and improves aero stability in crosswinds, offering better control at high speeds.
Aero-Optimised Geometry
Crafted using CFD (Computational Fluid Dynamics) and wind tunnel analysis, the Aero-Optimised Geometry delivers razor-sharp handling, rock-solid stability, and maximum speed efficiency during every phase of your race.
