Cube Aerium C:68X SLT Triathlon Bike in Liquid Blue Grid/Chrome

Season:2027

Brand:Cube

Code:1138700

Developed in collaboration with World Champion Lucy Charles-Barclay, the Aerium C:68X is the fastest frame Cube has ever made.

Every detail, from the aero fork design and disc brake integration to in-frame hydration and storage systems, has been designed with zero compromise. Tested in the wind tunnel and under pressure in race conditions, the frame features a high-rise bar for medium and large sizes.

The Aerium C:68X SLT features premium C:68X® carbon construction with flexible, adaptable hydration and storage options, including the ability to add up to two hydration systems for longer races. The Cube cockpit offers a wide range of adjustment, putting everything you need at your fingertips.

A Newmen Streem Aero 80/80 Vonoa wheelset, paired with Continental Grand Prix 5000 TT tyres, provides an aero match for the wind tunnel-tested frame. Shimano's Dura-Ace Di2 groupset, featuring 2x12 gearing, a 4iiii power meter, and hydraulic disc brakes, delivers precise shifts and controlled braking. A cover is included for the front derailleur mounting area if you choose to revert to 1x gearing.
