SL low

Ready for a new challenge? Want to test your own limits and leave the competition behind? The brand new Aerium C:68 SL is the perfect tool for the job. Developed in conjunction with the ærodynamics and Formula One specialists at Swiss Side, this no compromise speed machine leaves UCI regulations behind in the quest for ultimate performance. Wind tunnel testing, real world data-logging and fastidious attention to detail make this the fastest triathlon machine out there in our testing. Equipped with Shimano's new Ultegra components and Magura brakes, you've everything you need to set new personal records - and get your competition really worried.

There's more to developing a wind-cheating bike than giving it lots of 'æro' shaped tubes. That's why we worked with the development team at Formula One specialists Swiss Side, whose experience in reducing drag proved invaluable in building a new standard in triathlon bikes. Wind tunnel testing helped us to reduce the effects of crosswinds and turbulence, giving the Aerium C:68 SL not just incredible straight line speed but impressive stability out in real world riding conditions, too. Low seatstays help to reduce the frontal area, while the unique slotted head tube acts as a spoiler. The hydraulic brake system, developed in conjunction with Magura, is designed for quick wheel changing and easy adjustment - and, of course, all cables and hoses are hidden away, out of the wind. We even included food storage and drinking systems into the frame, both of which are accessible without moving from the æro riding position. We know from our testing that this is the best triathlon bike out there. All it's lacking... is you.

      • Advanced Twin Mold

        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.

      • C:68 Carbon Fiber Technology

        CUBE?s highly innovative new C:68 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.

      • Frame Safe System

        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.

  • Icon of CUBE technology Full DI2 Integration

      • Full DI2 Integration

        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.

      • Integrated Cable Routing

        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.

  • Icon of CUBE technology Press Fit BB
      • Image of CUBE technology Press Fit BB
      • Press Fit BB

        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.

  • Icon of CUBE technology Wet Paint Surface

      • Wet Paint Surface

        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.
