2026 Cube Aerium C:68X TT Bike Frameset - Carbon/Prism

Season:2026

Brand:Cube

Code:131110CBNPRISM

The Cube Aerium C:68X TT Bike Frameset is an elite-level carbon time trial frameset designed for riders who demand maximum aerodynamic efficiency, stiffness, and speed within UCI regulations. Developed by Cube Bikes using advanced engineering techniques including Computational Fluid Dynamics (CFD) modelling and wind tunnel testing, this high-performance TT frame is built to deliver marginal gains that translate directly into faster race times.


Ultra-Aerodynamic UCI-Compliant Carbon Frame

Constructed from Cube’s premium C:68X® carbon fibre, the Aerium C:68X TT frameset combines low weight, exceptional stiffness, and cutting-edge aerodynamic shaping. The frame has been meticulously engineered to reduce drag while maintaining compliance with UCI time trial bike regulations, making it ideal for competitive time trial racing, triathlon events, and professional cycling competitions.

Cube’s Advanced Twin Mold carbon construction ensures precise carbon layering and optimal strength-to-weight ratio, resulting in a frame that transfers power efficiently while maintaining stability at high speeds.


Wind Tunnel-Optimised Speed

The Aerium C:68X TT is designed to slice through the air with minimal resistance, using aerodynamic tube profiles and integrated design features refined through extensive wind tunnel development. Every surface and angle of the frame has been optimised to reduce turbulence and maximise efficiency when riding at race pace.

This results in a professional-level aero time trial frameset that helps riders maintain higher speeds with less effort, crucial for shaving seconds off your personal best.


Race-Focused Geometry and Cockpit Integration

Included with the frameset is the Cube Basebar TT cockpit with 0mm rise, enabling riders to achieve an aggressive aerodynamic riding position that maximises speed and power output. The geometry is carefully designed to support optimal rider positioning for time trials and triathlon racing, helping athletes maintain efficiency and control during high-intensity efforts.


Built for Marginal Gains

Every detail of the Aerium C:68X TT frameset is engineered to deliver the small aerodynamic and efficiency improvements that matter most in time trial racing. The result is a lightweight, stiff, and exceptionally fast carbon TT bike platform capable of performing at the highest level of competitive cycling.


If you're searching for a UCI-legal aero TT frameset designed for maximum speed and performance, the Cube Aerium C:68X TT is built to turn every watt into forward momentum.
