The biggest obstacle to going faster isn't you, it's air. Which is why, for the Aerium C:68X SLT Aero, we took a close look at our medal-winning race bike and fitted it with components that are to air what a hot knife is to butter. Profile Design ASC Pro extensions combined with our CUBE cockpit help put you in the most efficient aero tuck possible. And the Newmen Streem Aero/Disc TT80/Disc Vonoa wheelset – clad with Schwalbe Pro One Aero tyres – features a carbon disc rear to complement the deep-section front wheel. Sram S-900 Aero brakes are the finishing wind-cheating touch. Put it all together, and it means that more of your output will go into forward propulsion, transferred to the road via Sram's Red AXS 1x12 gears with a Ceramicspeed waxed Red chain and a Sram Red crank with built-in power meter. It's quick. You will be, too.<br><br><strong>Frame description</strong><br />Developed in close collaboration with CUBE athlete and World champion Lucy Charles-Barclay, the Aerium C:68X can rightly claim its title as the fastest frame we've ever made. Every detail, from the aero fork design, disc brake integration and in-frame hydration and storage systems has been designed with zero compromise, tested in the wind tunnel and then tested again under pressure, in race conditions. Lucy has full confidence in the frame and its configurable storage and hydration and now you can, too.
