AERIUM 2018:

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.

Rider and bike become one

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

We challenge the wind

That's when the hard work really began. We 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 our engineers to create an entirely new front end that's little short of astonishing. 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

We didn't stop there. Lowered seatstays reduce the frontal area even further, while optional storage and drinking compartments allow you to reach what you 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

Our 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.

The perfect fit

But that's just half the package. The other half is you – which is why 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.



Low/ High Base Bar – Options

These two handlebar options allow you to customise this racing machine to your own aero position.

Front Hydration and Storage Box System

Aerodynamic, perfectly integrated accessory that can be quickly attached and removed as needed thanks to its magnetic click system. The Front Hydration and Storage Box System is included with Aerium C:68 SLT and SL Series configuration options as well as with the frameset and fits perfectly onto the frame:

  • The BPA-free Hydration System has a capacity of 650 ml, is easy to fill and clean, and is hard to miss when you're riding in aero position.
  • The StorageBox, which has a padded bottom, gives you space where you need it: several energy bars or gels, or even a replacement tube and CO2 cartridge can be stored directly on the top tube.
The right power meter systems

The new Aerium C:68 SLT and SL Series model options are compatible with non-crank based power meter systems and the following crank-based power meters:

  • power2max
  • Quarq
  • Rotor 2inpower
  • SRM
Computer ready

The magnetically fixed stem cover allows you to optimally integrate your Garmin-, Sigma- or Wahoo bike computer into the bike’s aerodynamic design. The bike computer mount can be quickly and easily mounted, even if you are using the water bottle and storage box unit.*

(*computer mount is not included. Suitable mounts e.g. K-EDGE® - Garmin Replacement Insert Kit)

Rear Hydration

The seatpost-mountable PROFILE DESIGN RM10 has enough room for one to two additional water or tool storage bottles. (Not included)

Downtube Hydration

The frame's mounts are positioned so that aerodynamic water bottles can be carried in the optimal location.

  • Frame sizes S, M, L have two mounts
  • Frame size XS has one mount

Low- / High Base Bar - Options

The low option (flat bar) is 400 mm wide and optimised for maximum aerodynamic efficiency.

The sleek high option (riser bar) is 420 mm wide and 40 mm high, making reductions in aerodynamic drag possible that would otherwise require spacers.
