NO COMPROMISE.
NO LIMITS.

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.

Highlights
You've put in the hours, and now it's time to reap the rewards. The Aerium C:68X frame is the ultimate wind-cheating, watt-boosting machine for speed freaks. With its refined aero design and flexible build options, it's the performance boost you've been looking for.
  1.  
At CUBE much of our inspiration comes from working with athletes like World champion Lucy Charles-Barclay. While she hones her performance, we're busy building a bike that'll enable her to realise her potential even better. The Aerium C:68X combines sophisticated wind tunnel analysis with real world experience of racing. The result? Our most aerodynamic frame yet, with disc brake compatibility and a host of adaptable cockpit, storage and hydration options that are fully integrated so that everything is at your fingertips. Lucy particularly wanted to be as self-sufficient as possible, even on longer races, so we added the option of running up to two hydration systems in combination with our already well-established modular storage units – and an aero cover for the front derailleur mount means you can run 1x or 2x gears with no aero downside. Crafted from our premium C:68X® carbon, it's the hidden advantage you've been looking for.

Combining all our expertise from carbon frame building into the ultimate material, C:68X® carbon uses the optimum blend of fibre and nano particle-infused resin. Precision Advanced Twin Mold manufacturing means we can avoid bonded sleeves or inserts, too. It's the new benchmark for light, stiff and strong.
Set up your Aerium C:68X gears the way you like: as it's supplied, with a 2X system and front derailleur for the widest possible range of ratios, or switch to 1X for simplicity, low weight and optimum aero with the front derailleur mount neatly hidden behind its cover plate.
Full Internal Cable Routing takes the clutter of external cables and consigns it to the past. We started from scratch, designing frame and handlebars to accept gear and brake cables internally so that nothing interrupts the bike's clean lines. It's neater, it's more aero, it protects cables from damage and it reduces maintenance. All the wins.
The CUBE Aerium Cockpit System is about as configurable as it gets. The standard setup is Low, but there's an optional High setup too. With a wide range of adjustment for each, every rider can find their optimum position for comfort, endurance and performance. Armpads can be set over a huge range of widths and stack heights and saddle stack and reach is, of course, also adjustable. Because every watt counts...
Ultimate performance requires optimum hydration, and that means having a system that's accessible, adaptable and with enough volume for extended racing. The Hydration System 2.0 allows the rider to rehydrate without changing position, thanks to a configurable setup that includes a bar-mounted system plus an additional bladder located inside the frame, just above the bottom bracket.
Racers need sustenance, and that means having somewhere to store energy gels or bars. Our versatile, modular Storage System puts those extra calories within easy reach of the rider, without having to change position from an aero tuck. Set it up the way that works best for you, and then make use of the extra time you can save by having food close to hand. It's the little things that make the difference...
The Aerium's Twin Head Tube is visually striking, but it's not just about looks. Aerodynamically speaking, it helps reduce air resistance in a straight line for higher speeds. Which, of course, is what it's all about. And, with stronger cross winds, the twin tube profile helps reduce buffeting and increases steering stability. Win, win.
Air sucks, and that's why Aero Optimized Geometry matters. Developed with a combination of wind tunnel testing, Computer Fluid Dynamics and feedback from athletes, it's our way of ensuring you can get the best possible performance out of you and your bike. Stable when you need it, agile when it counts and above all very, very fast.
With our Advanced Twin Mold process we use two precisely manufactured forms for our C:62®, C:68® and C:68X® carbon frames. The first form is to ensure an accurate layup. The second, inner form keeps every individual fibre precisely where it needs to be while the frame cures. The result is a significantly lighter, stronger frame, with fibre density tailored to anticipated loadings at specific points.
Need more hydration or extra space for your kit? The Aerium C:68X has you covered. The compartment above the bottom bracket accomodates an extra hydration bladder, or you can use it carry essential spares like a CO2 cartridge, multitool and spare tube. And it's all fully enclosed and aero...
