The media circus around bike races, particularly big, tech-heavy ones like the Tour Auvergne-Rhône-Alpes (previously the Critérium du Dauphiné), is quite amusing sometimes, so indulge me for a second and I’ll lift the lid.

Some bikes we spot through nous, tip-offs, and a bit of sneaking. The new Specialized Tarmac Sl9 is one of those, but sometimes we just get told a bike will be available to come and photograph in advance of the race. The new Cube Litening Aero prototype is one such bike.

Here is the new Litening Aero. It’s quite similar in form to the old one, but with some significant changes. The curved seat tube remains, but the head tube and fork junction is more sculpted. The seat cluster has had the top lopped off it though in a way very reminiscent of the Cervélo P5 TT bike. (Image credit: Will Jones)

The cockpit, another new addition, is absolutely whopping. (Image credit: Will Jones)

The tops are VERY deep. Not quite as wide as the runway fitted to the old Dare V.A. of Uno-X, but not far off. Paired with what is quite a short stem it’s quite an unbalanced aesthetic. (Image credit: Will Jones)

While the fork is all pretty colours, it’s only a little deeper than the current model. The rear of the crown flows into the head tube and down tube much more elegantly though. (Image credit: Will Jones)

Theres a ridge in the head tube, much like the new Ridley lightweight machine I also saw at the race. Tyre clearance in those forks is big enough for standard 28c or 30c race tyres, but it’s not enormous. (Image credit: Will Jones)

These Newmen Streem wheels have hidden valves for an aero advantage, and by our testing it isn’t just marketing fluff, though it does make pumping them up a bit more of a chore. (Image credit: Will Jones)

The truncated seat cluster features a pretty standard ‘compensation triangle’ underneath. (Image credit: Will Jones)

The bottom bracket remains narrow for most of its volume, but is much wider where the stays intersect. It’s more like the stays join to the sides of the BB shell, rather than the rear of it. (Image credit: Will Jones)

The curved seat tube stays going forward. (Image credit: Will Jones)

The seatpost is clamped by two bolts in the rear of the seat tube, a well established system at this point. (Image credit: Will Jones)

The back side of the fork legs is your classic truncated aerofoil profile. (Image credit: Will Jones)

While the aesthetics are similar, with a pretty consistent design language, I actually think it’s quite a good looking bike. Also, having turned the bars, the steering lock that was quite annoying on the last one was nowhere to be seen. It may return for production models, though. (Image credit: Will Jones)
