CUBE (Germany) – “When we set out to develop the brand new Aerium C:68 we had a very simple goal: ultimate speed. No compromise, no ifs, no buts, nothing left on the table. And to achieve that, we had to rip up the rule book and start again. So we ditched UCI regulations, wiped the slate clean and asked Formula One experts Swiss Side to work alongside us in building a bike that's so slippery, the wind won't know what's hit it. To achieve this we had to take an entirely new approach. Instead of building a fast bike and then putting the rider on it as an afterthought, we took a holistic approach from the beginning”, stated CUBE.

Rider and bike become one:
Working with former Ironman record-holder Andreas Raelert, CUBE engineering team based all their modelling and real world testing on the concept of bike and rider as a complete package. They even created a virtual Raelert to use in our Computational Fluid Dynamics (CFD) modelling.



We challenge the wind:
CUBE created hundreds of CFD iterations involving both 2D and 3D models of individual frame sections, right up to the complete bike and rider. Extensive wind tunnel and real world testing with data-logging then allowed their engineers to create an entirely new front end that's little short of astonishing. According to CUBE, “the slotted head tube is supremely efficient in a straight line, but it's also adept at coping with cross-winds without losing the bike's composure. That way, you can concentrate on getting the power down without worrying about being blown off course”.

What you need, when you need it:
Lowered seatstays reduce the frontal area even further, while optional storage and drinking compartments allow the rider to reach what they need mid-race without coming out of an aero tuck. Cables and electronic components are seamlessly integrated into the frame, but easily accessible when the need arises.

Competitive design:
CUBE engineering team even developed completely new, integrated brake arms and levers to work with the frame's streamlining, and then enclosed the calipers in aerodynamic 2K injection mould housings. “Wheel changes take just seconds, even in the heat of competition. And horizontal dropouts mean you can fine-tune tyre clearance while preserving that all-important torsional rigidity for efficient power transfer”, CUBE says.

The perfect fit:
CUBE added, “we paid so much attention to getting the perfect fit between bike and rider. There's a huge range of adjustability to put you in the perfect ride position, including a choice of two handlebars, hundreds of combinations of pad height, width and reach and, of course, saddle position”.

Twin Head Tube:


The Twin Head tube is not only a striking visual detail, but also an important building block in the overall aerodynamic concept of the new AERIUM C:68. At low inflow angles, the Twin Head tube acts like an aerodynamically optimally long profile, which leads to a reduction of the air resistance. At medium and high inflow angles, the flow field in the control tube area is so ideal that it significantly improves the sail effect with the simultaneous reduction of the side wind susceptibility. In short: Maximum aerodynamic performance paired with ideal handling.

Concept Front Hydration & Gear Box:


Aerodynamics and ergonomics are key factors for a fast bike split. This is why our aerodynamic team has developed an integrated beverage and storage system, which allows for an optimal care even in the aerodynamic position.

C:68 Carbon Fiber Technology:


CUBE’s highly innovative new C68 carbon fibre technology allows us to build better bikes than ever. Typically, carbon fibre frames are around 60% carbon fibre, with the rest being the resin that bonds the fibres together. By distributing carbon fibres evenly, we can make thinner layers within the frame and reduce the amount of resin. Those fibres are a mixture of Ultra High Modulus, High Modulus Spread Tow and Intermediate Modulus carbon, each chosen for the needs of the particular area of the frame. Nanoparticles within the resin itself allows it to be distributed more evenly when under pressure in the frame mould. The result is a range of frames with 68% carbon fibre – lower weight, higher stiffness, more fun.
