Cycling & Aerodynamics Leaders Join Forces To Develop World's Fastest Time Trial Bike

Collaborators CUBE, a leader in bike manufacturing, and Swiss Side aerodynamic experts, have formed an official partnership. By combining their respective areas of expertise, the two brands have pursued a goal to develop the fastest time trial bike in the world. This bike has the most aerodynamic carbon frame ever creating forward motion in its purest form. CUBE and Swiss Side teamed up for the first time in 2015 and the results were phenomenal. The CUBE Aerium C:68 high-end triathlon bike was modified and adapted in the wind tunnel in Immenstaad on Lake Constance by CUBE and Swiss Side as part of the joint Raelert Brothers' sponsorship. Runner-up World Champion, Andy Raelert rode this “ultimate aero bike” to an impressive second place finish at the 2015 Ironman World Championships in Kona, Hawaii.

The CUBE Aerium C:68 was put through a battery of wind tunnel testing by Swiss Side’s expert aerodynamics team and modified for best possible performance. The bike was then equipped with Swiss Side HADRON Ultimate 800+ aero wheels and ultimately saved Raelert 10 plus minutes over the 180 km bike course. The new CUBE Aerium C:68 is now available to the public which makes it possible for all triathletes to benefit from 'Aerodynamics by Swiss Side'.

This year, the engineers at CUBE are, once again, working together with the aerodynamics experts at Swiss Side to create a world-class bike for the 2016 Ironman World Championships in Kona, Hawaii. Raelert's new prototype bike will allow extra valuable minutes to be shaved off the bike course time thanks to the optimisation of the entire rider-bike system. With over 50 years of Formula 1 experience, Swiss Side’s engineering team is number one in aerodynamics, bringing the latest technologies to cycling research and development. Raelert’s new time trial bike was developed with development methods used in Formula 1, including analyses computational fluid dynamics (CFD), wind tunnel testing, performance simulations and measurements with the unique Instrumented Bike.

"CUBE is a big name in the cycling industry and the right partner to put our Formula 1 expertise to constructive use,” says Jean-Paul Ballard, Swiss Side's technical director. “This partnership guarantees the development of a triathlon bike that will set new standards in the bike industry.” 

The CUBE development team are also convinced that the prototype will set a new benchmark for the triathlon segment,” says Bernd Schenkl, Head of Engineering at CUBE. “Our goal is to build the fastest triathlon bike in the world. The current prototype is the product of a two-year development phase, during which, we worked closely with Swiss Side to create a world-class aero bike for Andy Raelert. Our focus was on combining uncompromising aerodynamics with a unique design to build a bike that is not only the fastest in wind tunnel tests, but one that also delivers outstanding maneuverability and plenty of set-up options to allow athletes to find the perfect riding position. This approach is crucial to ensuring maximum on-road performance. The innovative C:68 carbon frameset transforms every watt of energy expended at the pedals into speed and perfectly combines a lightweight structure with extraordinarily high stiffness and ultimate aerodynamics.”

The Raelert brother’s new CUBE racing machines proudly carry the 'Aerodynamics by Swiss Side' logo. The bike setup is equipped with Swiss Side HADRON Ultimate 800+ aero wheel, independently confirmed to be one of the world’s best aerodynamic wheelsets. Swiss Side wheels are naturally also developed with the same outstanding methods directly from Formula 1 aerodynamics.

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.

Redefining aerodynamic development in the cycling industry, this unique interconnected development process is designed to perfectly match reality, for delivering 'real world performance’ out on the road where in matters.

  1. CFD (Computational Fluid Dynamics):  More advanced than any other in the cycling industry. Using the latest CFD technologies from Formula 1, including real time ‘transient’ flow models of the complete bike and rider. Backed up with extensive wind tunnel correlation, Swiss Side’s CFD methods are second to none in terms of closeness to reality.
  2. WIND TUNNEL:  Swiss Side’s wind tunnel testing methods are the most advanced in the cycling industry. Using unique systems such as steering torque measurement and rider laser positioning systems, the result is an unparalleled wind tunnel development capability.
  3. INSTRUMENTED BIKE:  The most advanced on-bike aerodynamic measurement system ever seen. Using an array of sensors to measure aerodynamics out on the road and importantly, how the rider reacts, this unique system delivers 'real world data' about aerodynamic performance for BETTER UNDERSTANDING = BETTER PERFORMANCE.
  4. PERFORMANCE SIMULATION:  Quantifying ‘real world performance’ to direct development where it matters. Swiss Side’s simulation tools allow the time won or lost to be calculated for any design or setup, over any course for any rider, in any conditions. Like this, performance can be quantified at any point during the development phase to make the best design decisions.

        This technique uses a complete core to provide the perfect frame form during the lay-up process. As with the Twin Mold technology, precise inserts are used to ensure extra strength at high-stress frame points. This combination offers maximum control over fibre orientations during the lay-up and production process. The Advanced Twin Mold high-tech carbon manufacturing process translates to outstanding product safety and quality together with optimum weight and stiffness characteristics.

        Perfect aerodynamics and geometry adjustment characterize this package to the smallest detail the light and stiff Advanced Twin Mold carbon frame with horizontal dropouts is designed for the use of electronic circuit components to minimize air resistance. Battery and cable are hiding elegantly in the framework and also the brakes fit perfectly together with the Aerium Super HPC carbon fork.

        To protect our high-end aluminium frames from damage, they are built with the CUBE Frame Save System replaceable derailleur hanger. The mounting thread is in the hanger and not in the frame as usual. In case of a crash, this hanger can be easily and quickly replaced by a new one.

        Internally routed cables offer many advantages. Cables are protected from dirt for longer life, weight is saved thanks to the absence of external housing and the bike has a clean, sleek appearance.

        With Press Fit bearings, the bottom bracket bearings are pressed directly into the frame and not screwed in as usual. This gives a wider bottom bracket shell and allows us to build a wider down tube and more broadly-spaced chainstays. Every millimetre of additional width gives a significant improvement in lateral stiffness.

        On polished, brushed aluminium and all HPC frames, the logos and graphics are applied in multi-layer wet paint. We use this surface treatment technology mainly to save weight.

        Trough the full Di2 Integration the Dura Ace Di2 battery is completely fitted within the frame. The Shimano junction box is placed aerodynamically in the stem which makes charging and servicing a lot easier as it can be done via the junction in the stem. Another distinct feature is that it can be easily dismounted and mounted for transporting the bike.
