Cube Aerium C:68X Pro TT Bike 2027 Engineered in close collaboration with Ironman World Champion Lucy Charles-Barclay, the Cube Aerium C:68X Pro 2027 is an uncompromising time trial and triathlon bike built for pure speed. Tested extensively in the wind tunnel and proven under intense race conditions, its C:68X monocoque carbon frame represents the pinnacle of aerodynamic design, incorporating an aero fork and flat-mount disc brake integration to minimize drag. Beyond raw aerodynamics, the frame features fully customizable in-frame hydration and modular storage options, allowing triathletes to execute their nutrition strategy seamlessly without disrupting their aero tuck. Designed to translate maximum effort into course-record times, it delivers an ultra-slippery profile, exceptional power transfer, and steady handling when battling crosswinds. Integrated Cockpit Efficiency and Race-Tuned Carbon Wheels To ensure you stay locked in the optimal position, the bike features the size-specific Cube Aerium C:68X Cockpit System, utilizing a dedicated high-rise setup for medium and large sizes to enhance long-distance comfort and overall aerodynamic efficiency. Contact points are refined with Acid Bartape RC 2.5 and a triathlon-specific Acid Athis saddle mounted to the dedicated Aerium C:68 Aero seatpost. Rolling stock consists of a deep-section Newmen Advanced A.50 SJ Carbon wheelset, paired with high-performance 28mm Schwalbe Pro One Aero tyres to keep rolling resistance low and traction secure through high-speed turns, ensuring maximum momentum is preserved over every segment of the course.
