The Fastest Triathlon Bike: Cube Aerium C:68X

no compromise, no limits.

cube aerium

the ultimate triathlon bike

The new Aerium C:68X is all about aerodynamics. But that's not all. With the extremely high-quality C:68X carbon, the frame is feather-light and uncompromisingly stiff. This means that every watt you pedal is immediately converted into pure speed. This bike is truly unbelievably fast. How do we know that for sure? The wind tunnel is the proof.

The wind tunnel tests confirm it: the Cube Aerium C:68X is unprecedentedly fast and advanced.

Developed in close collaboration with triathlon world champion Lucy Charles-Barclay, the Cube Aerium C:68X embodies the essence of speed. This bike is designed with one clear goal: minimize drag to give triathletes the fastest possible performance.
Every detail of the bike, from the frame construction to the integrated systems, has been fine-tuned for maximum aerodynamics. The result is a machine that gives you the edge over the competition, without compromising stability or comfort.

more aerodynamic than ever

The higher the speed, the more the air pushes and pulls at you. That’s where Cube’s Aero Optimized geometry comes in. Created using wind tunnel testing, computational fluid dynamics and of course the input of professional athletes, you can be sure that you’ll get the best possible performance from yourself and your bike. Stable when it needs to be, agile when it matters and of course fast. Really fast.

high-quality carbon frame

The Cube Aerium C:68X uses the advanced C:68X Monocoque Carbon technology, where every detail of the frame is tuned for maximum speed and minimum drag. By developing the frame using Advanced Twin Mold Technology and high-quality carbon fiber materials, this bike is not only ultra-light, but also extremely stiff. This means that every watt you pedal is converted into pure speed.

hydration system 2.0

You can train as much as you want, but without enough fluids on race day you are hopeless. Our Hydration System 2.0 makes it possible to drink without having to change your sitting position. The entire system can be positioned to your personal preference and also includes an extra drinking bag inside the frame, just above the bottom bracket.

ultimate comfort

The Selle Italia Watt SF Magnesium saddle on the Cube Aerium C:68X SLX is specifically designed to provide triathletes with maximum efficiency and comfort over long distances. With its wider nose and ergonomic shape, this saddle offers greater stability in the aerodynamic racing position, essential for top performances. The magnesium rails provide an excellent balance between light weight and durability, while the anti-slip coating ensures you stay firmly in place, even during intense rides.

integrated cables

Cable salad on the outside of your frame? Cube's fully internal cable routing puts an end to that once and for all. It looks simple, but a lot of time has gone into aligning frame, components, cables and pipes. We think the result is impressive. Tight and aerodynamic.

aerium cockpit system

It doesn't get more versatile than the CUBE Aerium Cockpit system. In the standard configuration, the handlebars are low, but a high setup is also possible. Thanks to the countless adjustment options, every cyclist can achieve an optimal position for optimizing comfort, performance and endurance. The armrests are adjustable in length, width and height. After all: every watt counts...

coverable front derailleur

You can configure the drivetrain of the Aerium C:68X as you wish. With a double or a single chainring. In the latter case, you can aerodynamically cover the unused mounting point of the front derailleur with a special cover plate.

various storage options

During long races, triathletes need fuel like energy gels or bars, and that means you need a place to easily store it. The Cube Aerium C:68X’s versatile, modular storage system keeps that extra energy within reach without having to move from your aero position. It’s adjustable to your needs, so you can grab your nutrition at a moment’s notice and save precious time. It’s small details like this that make all the difference in your racing performance.

extra storage space
Need more space for your hydration? Or for extra gear?

On the Aerium C:68X that is no problem. The space above the bottom bracket fits an extra drinking bag. Or you can store your CO2 cartridges, spare tire and multi-tool. In all cases without loss of speed, because the storage space is completely aero!

Optimized for Speed

The Newmen Advanced SL R.80 Streem Carbon wheelset is designed for pure speed and aerodynamic efficiency. With an 80mm rim profile and a mere 1740g, these wheels are perfect for time trial and triathlon competitions where speed is the top priority. Thanks to the 22mm internal width and the hook design, wider tires can be used, which increases comfort without sacrificing aerodynamics.

twin head tube

The Twin Head Tube, the double head tube, of the Aerium C:68 is a real eye-catcher. But that is not what it is about. What is important is that this construction reduces air resistance, especially at high speed on straight stretches. With the added value that the Twin Head Tube reduces vibrations from the front in the wind and improves the stability of the bike. Win win, we call that.
