Cube Aerium C:68X Race Dura Ace Di2 Triathlon Bike
Developed in close collaboration with World Champion Lucy Charles-Barclay, the Aerium C:68X SLT frame’s premium C:68X® carbon construction incorporates adaptable hydration and storage options, including the capacity to add up to two hydration systems for longer races. The CUBE cockpit puts everything at your fingertips, offering a wide range of adjustments. A Newmen STREEM Aero/Sprint TT 60/80 Vonoa wheelset, paired with Continental Grand Prix 5000 TT tyres and aero valves, is the perfect aerodynamic match for the wind tunnel-tested frame, giving you extra watts for faster progress. Shimano’s renowned Dura-Ace Di2 groupset, featuring 2×12 gearing, a built-in powermeter, and hydraulic disc brakes, ensures precise shifting and responsive braking. Additionally, if you prefer to switch to 1x gearing without a front derailleur, an aero cover preserves the frame’s performance.
