Athletes never stop chasing their goals, and neither do we. The Aerium C:68X SLX represents the pinnacle of our carbon manufacturing technology, combined with sophisticated aero analysis and the power of disc brake control. The bottom line? Simply this: it redefines speed.

You know this bike is fast, because the Aerium C:68X SLX is closely based on triathlete Lucy Charles-Barclay's World Championship-winning bike. Configurable hydration and storage options sit behind aero hatches, adding the ability to run up to two hydration systems for better self-sufficiency, even during long races. We fitted a Newmen STREEM Aero/Sprint TT 6/8 Vonoa wheelset shod with Continental Grand Prix 5 TT tyres and aero valves for rapid acceleration, superior aero performance and safe cornering grip. The Cube C:68X cockpit system puts the rider in the optimum position, with a huge range of adjustment for the aero bars. A SRAM Force AXS 2x12 drivetrain with built-in powermeter ensures the right gear is always right there. And absolutely all of it is crafted from our premium C:68X carbon. We sweated the detail, so your sweat can be translated into pure speed.

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.

Features

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. 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 Optimised 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...
