Technical specifications
Description
Made for race-day focus:
The Aerium C:68X frame uses CUBE’s Monocoque Advanced Twin Mold Technology, with full internal cable routing and disc brake integration for a clean, streamlined setup. The matching Aerium C:68X fork keeps the front end tidy too. The result is a bike that feels purposeful and ready to stay sharp when the pressure is on.
A cockpit that supports the effort:
The Profile Design ASC Pro extensions and CUBE Aerium C:68X cockpit help place you in a more efficient aero position. That matters when you want to hold speed without wasting energy. It is the sort of setup that feels like it disappears beneath you and lets you focus on the effort ahead.
Fast, direct, and race-ready:
The Newmen Streem TT.80/Infinite VONOA carbon wheelset brings a deep, aerodynamic setup, with a carbon disc rear wheel and Schwalbe Pro One Aero tyres. Shimano-free speed is not the story here - this build uses SRAM Red AXS 12-speed gearing, paired with a Red crank with built-in power meter and a Ceramicspeed wax-coated chain. It is a clean, race-focused drivetrain made to keep the power delivery crisp and direct.
For the long effort:
This bike is built for riders who want their kit to work with them, not against them. The hydration and storage systems are part of the design, so you can stay focused on the ride instead of the logistics. It is a serious machine, but it still feels human when you are in the saddle.
