The end result of this sophisticated manufacturing process is a frame with more rigidity and compliance exactly where it’s needed for a more comfortable but safer frame. The texture of the resin was improved too, adding nanoparticles to help make it stronger and then the Cube engineers cleverly specified a range of different fibre choices and orientations allowing them to add controlled amounts of stiffness or compliance to separate areas of the frame and fork as required.Ĭube used up to six different fibre types in the carbon layup process to help save weight while increasing aerodynamic efficiency, with fibres on each section of the frame being utilised according to load – more materials for weight bearing portions, less materials for portions that don’t carry so much load. C:68X sees a dramatic reduction in the amount of resin used in production, bringing down the level to just 32%. C:68X is Cube’s premium carbon fibre which magically blends strength and low weight in one brilliant material. With a slightly translucent finish you’re able to see the carbon fibre weave throughout the frame and can’t help noticing the beauty and sophistication of how the frame has been crafted. The iridescent finish on the Litening C:68X SL is something to behold as you move around the bike the colour appears to move over the bike. The iridescent finish on the Litening C:68X SL is something to behold. As our Giro d’Italia stage winner has already proved, in a world of marginal gains that’s enough to make the Litening C:68X SL a genuine breakaway machine. This painstaking process paid off with the Cube engineers reporting a 30% improvement in drag reduction compared to the Litening’s predecessor. To do this Cube spent endless hours number crunching and using CFD (Computational Fluid Dynamics) backed up by extensive wind tunnel testing each and every component-part of this road bike’s chassis. In the pursuit of pure and sustained speed the engineering team at Cube wrote themselves a very simple brief – make the Litening’s frame, fork, seatpost, integrated bar and stem as slippery as possible through the air. The super-slippery Litening C:68X SL has been designed to be as aerodynamic as possible. So if we wanted proof that this top-of-the-range carbon aero road bike from Cube can hold its speed over long distances and is able to cut through the air efficiently then we’ve already got it now let’s take a closer look at what makes this bike so fast… The aero-efficient Cube Litening C:68X SL was piloted to victory on Stage 3 of this year’s Giro by Intermarché-Wanty-Gobert rider Taco van der Hoorn after he took an extremely close win, holding off the bunch sprint behind him to take the win after an audacious all-day breakaway. It’s Fast Bike Friday! This week we’re casting an eye over a super-slippery aero road bike that’s already proved itself in winning moves at races including the prestigious Giro d’Italia.
