Cube Aerium C:68X SLT TT Bike 2027 Developed in close collaboration with World Champion Lucy Charles-Barclay, the Cube Aerium C:68X SLT 2027 represents the pinnacle of time trial and triathlon performance. Constructed from Cube's premium C:68X monocoque carbon, this ultra-slippery chassis features an integrated aero fork, full internal cable routing, and a clean flat-mount brake design engineered to slice through wind resistance. To support peak endurance, the frame incorporates modular, aerodynamic storage and hydration solutions behind sleek hatches, allowing triathletes to configure up to two hydration systems. Designed with modularity in mind, the frame even features a custom cover for the front derailleur mount, preserving smooth airflow if you choose to run a streamlined 1x drivetrain setup. Precision Aero Cockpit and Deep-Section Carbon Wheels Creating an aggressive yet sustainable aero tuck is effortless thanks to the highly adjustable Cube Aerium C:68X Cockpit System, featuring size-tuned high-rise options on medium and large frames. For maximum momentum on flat and rolling terrain, the bike rolls on a deep-section Newmen Streem TT.80 VONOA Carbon wheelset with ultra-stiff carbon spokes. Paired with 28mm Continental Grand Prix 5000 TT TR tubeless-ready tyres, this wheel combination delivers instantaneous acceleration, elite rolling efficiency, and rock-solid cornering grip to keep you pinned through high-speed turns. Flagship Shimano Dura-Ace Di2 Electronic Groupset with Dual-Sided Power Powering this range-topping machine is Shimano's flagship 12-speed Dura-Ace Di2 electronic drivetrain, delivering instant, flawless shifting controlled right from the aero extensions. The massive 54x40T Dura-Ace crankset is factory-fitted with a dual-sided 4iiii Precision 3+ power meter, giving you live, pinpoint output data to fine-tune your race pacing strategy. Combined with a close-ratio 11-30T cassette, you can maintain your exact cadence at top speed, while matching Shimano Dura-Ace hydraulic disc brakes provide smooth, dependable stopping power when carrying speed late into technical corners.
