2026 Cube Aerium C:68x SLT Aero - Carbon Tri / TT Road Bike - Genesis Grid / Black

Season:2026

Brand:Cube

Code:131410

The Cube Aerium C:68X SLT Aero (2026) is designed for riders chasing the absolute pinnacle of triathlon and time trial performance. Every element of this bike is dialled in, from its wind-tunnel-tested Aerium C:68X Monocoque Advanced Twin Mold frame to the wireless SRAM Red AXS 12-speed groupset. Built around race-proven input (including work with Lucy Charles-Barclay), this model maximises aero advantages: fully integrated cockpit, internal routing, aero-optimised fork and head tube, and deep TT/tri wheelset. The SLT Aero isn’t just fast in a straight line; it’s built for confidence, precision, and marginal gains that make a difference when the stakes are highest.

The component spec is elite. Newmen Streem carbon TT.80 / full disc setup, aero tyres (Schwalbe Pro One Aero), and SRAM S-900 Aero HRD brakes give high-speed braking control and reduced drag. Every watt saved matters here, whether on the flats or powering up small inclines in a triathlon. For those who race, want to PB, or compete in Ironman events, the SLT Aero delivers class-leading efficiency, control, and integration.

Professional Opinion
  • C:68X Carbon Fiber Technology
    Combining all our expertise from carbon frame building into the ultimate material, C:68X® carbon uses the optimum blend of fibre and nano particle-infused resin. Precision Advanced Twin Mold manufacturing means we can avoid bonded sleeves or inserts, too. It's the new benchmark for light, stiff and strong.
  • Front Derailleur Cover Plate
    Set up your Aerium C:68X gears the way you like: as it's supplied, with a 2X system and front derailleur for the widest possible range of ratios, or switch to 1X for simplicity, low weight and optimum aero with the front derailleur mount neatly hidden behind its cover plate.
  • Full Internal Cable Routing
    Full Internal Cable Routing takes the clutter of external cables and consigns it to the past. We started from scratch, designing frame and handlebars to accept gear and brake cables internally so that nothing interrupts the bike's clean lines. It's neater, it's more aero, it protects cables from damage and it reduces maintenance. All the wins.
  • Aerium Cockpit System
    The CUBE Aerium Cockpit System is about as configurable as it gets. The standard setup is Low, but there's an optional High setup too. With a wide range of adjustment for each, every rider can find their optimum position for comfort, endurance and performance. Armpads can be set over a huge range of widths and stack heights and saddle stack and reach is, of course, also adjustable. Because every watt counts...
  • Hydration System 2.0
    Ultimate performance requires optimum hydration, and that means having a system that's accessible, adaptable and with enough volume for extended racing. The Hydration System 2.0 allows the rider to rehydrate without changing position, thanks to a configurable setup that includes a bar-mounted system plus an additional bladder located inside the frame, just above the bottom bracket.
  • Storage System
    Racers need sustenance, and that means having somewhere to store energy gels or bars. Our versatile, modular Storage System puts those extra calories within easy reach of the rider, without having to change position from an aero tuck. Set it up the way that works best for you, and then make use of the extra time you can save by having food close to hand. It's the little things that make the difference...
  • Twin Head Tube
    The Aerium's Twin Head Tube is visually striking, but it's not just about looks. Aerodynamically speaking, it helps reduce air resistance in a straight line for higher speeds. Which, of course, is what it's all about. And, with stronger cross winds, the twin tube profile helps reduce buffeting and increases steering stability. Win, win
  • Aero Optimized Geometry
    Air sucks, and that's why Aero Optimized Geometry matters. Developed with a combination of wind tunnel testing, Computer Fluid Dynamics and feedback from athletes, it's our way of ensuring you can get the best possible performance out of you and your bike. Stable when you need it, agile when it counts and above all very, very fast.
  • Advanced Twin Mold
    With our Advanced Twin Mold process we use two precisely manufactured forms for our C:62®, C:68® and C:68X® carbon frames. The first form is to ensure an accurate layup. The second, inner form keeps every individual fibre precisely where it needs to be while the frame cures. The result is a significantly lighter, stronger frame, with fibre density tailored to anticipated loadings at specific points.
  • Extra Storage
    Need more hydration or extra space for your kit? The Aerium C:68X has you covered. The compartment above the bottom bracket accomodates an extra hydration bladder, or you can use it carry essential spares like a CO2 cartridge, multitool and spare tube. And it's all fully enclosed and aero...
