The Litening feels stiff and direct, but to get a comfortable ride in UK conditions, you might need a swap from the 25mm Schwalbe Pro One tyres with inner tubes that we rode to tubeless 28mm tyres, for which there’s clearance and wheelset compatibility.Litening C:68X Monocoque Advanced Twin Mold Technology, Aero Headtube, Full Integrated Cable Routing, Flat Mount DiscĪCROS, Top Integrated 1 1/8", Bottom Integrated 1 1/4" Weighing around 7.6kg, the bike is pretty light for an aero machine equipped with the disc brakes that are rapidly taking over on performance bikes, so uphill wasn’t a problem either. Cube seems to have done a really good job of sorting the Litening C:68X’s handling in these kind on conditions, suggesting those 1000 hours of testing has been put to good use.ĭescending, the Litening was fast and assured. Although the stop on the bar rotation feels disconcerting when you’re stationary, in practice it doesn’t affect manoeuvrability when riding, unless you’re planning to track stand or try some other low speed tricks.Īround where I ride it can get a bit blustery, but I didn’t feel any twitchiness when riding in crosswinds. I liked the wide, flat tops of the aero bars they’re comfortable to rest your hands on, distributing pressure well.
This certainly felt like the Litening’s natural environment, unlike its predecessor, which would have been a little laboured at such speeds on fast flat roads. Hitting the gas on flat rides the bikes easily hits a 40kph speed, that isn’t usually my bad when it comes to riding bikes. The result is a significant 30 reduction in drag, in a fully UCI-compliant frame that elegantly integrates fork, stem, handlebar and seatpost. It’s a bike that wants to be ridden fast. The Litening C:68Xs lightweight carbon chassis - built with our premium C:68X material - was designed with extensive use of Computer Fluid Dynamics and real-world wind tunnel testing. Running a wider rear tyre doesn’t impact aerodynamics though. There’s clearance for 28mm tyres and some 30mm tyres will fit when paired with some rims.īut it says that it found optimum aerodynamics with narrower front tyres and says that it’s important to preserve the gap between the fork crown and the tyre to keep the aero benefits when this gap is too narrow, additional turbulence and drag ensue. But Cube looked to add compliance, building 20 prototypes to optimise the carbon lay-up while maintaining strength and safety.Ĭube has aero tested the Litening C:68X with a range of wheelsets and tyres. Because of their wider section, aero posts often transmit road buzz and bumps to the saddle.

Plus it’s compatible with K-Edge adapters for Lezyne units and GoPros.Ĭube has worked on the Litening C:68X’s seatpost design too. It comes with an adaptor for Wahoo Elemnt computers as well as Garmin units. So Cube has developed its own Garmin mount that positions the computer lower down and out of the airflow. There’s not much point in having an aero cockpit if a bike computer sticks up above it and disrupts the airflow. But it says that, as with the Scott Addict, there’s enough room to use mechanical cables to the shifters too. So far, all of Cube’s Litening C:68X test bikes have been built up with electronic transmissions, either cabled or wireless, including the SRAM Red eTap AXS-equipped bikes that we tested at the launch. That results in quite a chunky profile to the stem and Cube has included a stop to prevent the bars from rotating too far and damaging the cables. But Cube has passed the cables and brake hoses round the sides of the steerer tube, entering the frame behind it. Hidden cables normally pass either in front of the headset bearings or through them. With the round section of external cables generating significant drag, it’s an area where there are still aero benefits that manufacturers are now looking to exploit. Integrated bar and stem and fully internal cable routing. Like many of the latest crop of bikes, including the just-launched Scott Addict RC and Wilier Zero SLR climber’s bikes, Cube has also enhanced its cockpit integration, with a one-piece bar/stem and internal cable routing. Redesigned frame for 2020 with 30 reduction in drag over previous model. And Cube 3D printed many different bar shapes and wind tunnel tested them. So the head tube, for example, is waisted. Cube concentrated on reducing the Litening C:68X’s frontal area, again while skimming the UCI regs.
