Over at the newly-named Tour Auvergne-Rhône-Alpes (the Critérium du Dauphiné to you and I), we spotted what could be one of the most affordable aero road bikes of 2026.
Cube is on a bit of a roll at the moment. Its well-priced road bikes are gaining massive popularity because, as is the case with the Litening Air C:68X, they are also excellent to ride. But the brand’s aero racer is a little long in the tooth. Recent photos of Total Energies’ bikes, however, suggest that there is something very special in the works.
For now, the only details that Cube will share is that this is a Prototype, but there is plenty that we can tell about the bike after I successfully negotiated access.
The new bike features a much tidier silhouette. Gone are some of the angular frame shapes that I will admit, I had trouble liking. The danger of this would be that Cube’s new bike morphs into obscurity amid an ever consolidating aero bike blueprint. But there is enough here to keep things distinctive.
One of the main changes at the front end of the bike is a set of deeper fork legs. Material seems to have been added behind and ahead of the front axle. It’s a move that plenty of brands have taken, seeking to exploit the UCI’s additional frame dimensions for a reduction in drag.
The changes continue at the top of the fork. A more angular design can be found in the head tube area, behind the fork crown. This may be to tidy up the messy airflow off the top of the front wheel.
It’s a similarstory at the upper part of the head tube, where a distinct fold line can be seen under the team’s bright white paint.
Moving up again, you’ll find what appears to be a new bar. This one-piece design features much deeper tops along with a less angular stem section.
That said, I am surprised to see very little flare in the drops. Canyon’s CP0053 Race Cockpit launched along with the brand’s new Endurace and is now an option for the Aeroad too. It gets a healthy 14º of flare, giving the rider more width in the drops while keeping their position on the hoods, very aero.
Speaking of the hoods, we were given access to Matteo Vacher’s Dauphine race bike. I measured his bars at 37cm wide at the hoods.
Away from the front end, Cube’s new bike looks to have a slightly deeper down tube. The Cube branding here is large, yet there is visible additional space around it. Usually, such a downtube would come with many aero claims attached to it, but while Cube were happy for us to see the new bike, not a single tech detail was divulged.
Towards the rear of the bike, the winds of change continue to blow. The seat stays are still deep, likely remaining for aero and stiffness purposes, though they now appear to flow into the seat tube at a slightly lower point than previously.
The move is most likely in pursuit of an aero saving, though there may be a little more rear end deflection in the mix too.
I’m certainly a fan of the seat tube changes. This still hugs the rear wheel, though it doesn’t rise above the seat stays as it did before. It also drops away at the seat post junction, presumably for comfort.
One final, puzzling detail is the lack of aero bottles. These seem like a relatively easy way to save some watts, though it would likely cause a bit of a headache given only two Total Energies are using the new bike at this race.
While lots of new bikes pass my eyes, I’m quite looking forward to getting the tech details, and more significantly, the pricing for this new bike.
Cube’s current Litening Aero C68X costs £7,499 for a build similar to that of Total Energies’. When I ranked the 2026 World Tour bikes, Total’s Cubes weren’t included as they are a Pro Tour team. But as a prominent French outfit, they have secured an invitation to the Tour de France.
From the list of Tour de France teams, only two have more affordable bikes. PicNic PostNL’s Lapierre bikes are £7,099, while XDS Astana’s X-LAB AD9 bikes can be built for around £6,300. That said, the latter figure is something of an estimation given no full build exists in the UK at this time.
With other brands reducing their prices for their latest models, I hope Cube’s bike offers riders a more affordable pro peloton race bike.

Why is the lack of aero water bottles that much of a surprise? Apart from in TTs many professional teams don’t bother with them, including the big two of UAE and JVL, in fact I can only think of LIDL Trek amongst the big teams that use them. Most teams seem to have decided that the +/- 3W saving is outweighed by various factors including cost (professional teams go through about 60,000 bottles a year so even a few pounds in cost difference will mount up), ease of use (much easier to grab standard bottles at feed stations) and interchangeability (having cages that can fit bottles from neutral service and sometimes other teams, if they are feeling generous).
