Team TotalEnergies will race a new Cube Litening Aero C:68X on today\u2019s first stage of the 2026 Tour Auvergne-Rh\u00f4ne-Alpes (formerly known as the Crit\u00e9rium du Dauphin\u00e9).<\/p>\n

The bike technically remains unreleased, with the team and brand tight-lipped on details, but it is distinctive for its sloping seat post insertion point.<\/p>\n

\"UnreleasedThis unreleased bike appears tidier than the current model, and the seatpost collar design has changed. Ashley Quinlan \/ Our Media<\/p>\n

Most bikes have a \u2018level\u2019 collar zone around the circumference of the seat post, but the new Cube\u2019s tapers dramatically at the rear, exposing more of the seatpost behind.<\/p>\n

In theory, this could allow the seatpost to flex more to improve compliance, but in this instance the seatpost has a distinctive teardrop shape. Here, this could have been optimised aerodynamically beyond the typical flatback designs often seen, but with compliance gained back through the extra exposure.<\/p>\n

\"UnreleasedTwo bolts fasten it in place as before, but the seatpost is now more ovalised. Ashley Quinlan \/ Our Media<\/p>\n

Given the seat tube tapers around the rear tyre, there isn\u2019t a lot of insertion space, so the two fixing bolts on the rear of the seat tube are likely there to serve as two fastening points for a wedge clamp.<\/p>\n

Despite this, the inside corner of this junction remains \u2018filled in\u2019, and as with the current bike it\u2019s likely purely for aerodynamic gain (given the seatpost clamp isn\u2019t housed here).<\/p>\n

\"UnreleasedUp front, things are fairly standard. Ashley Quinlan \/ Our Media<\/p>\n

The seat stays join to the seat tube in a dropped position, but with a tapering flare to the rear axle.<\/p>\n

At the front, things are more typical of aero and all-rounder race bikes. Matteo Vercher\u2019s bike pictured is a size 50cm, but the head tube and down tube are very deep but narrow, arguably pushing up to the limit of the UCI\u2019s 8:1 tube ratio regulation.<\/p>\n

\"UnreleasedTyre clearance is unconfirmed, but looks wider than the current bike’s 31mm. Ashley Quinlan \/ Our Media<\/p>\n

Cube appears to have stuck with a standard headset and steerer layout, as opposed to an offset bayonet design as seen on the Factor One<\/a>, Cerv\u00e9lo S5<\/a> and Colnago Y1Rs<\/a>.<\/p>\n

Tyre clearance appears to be upped from the 31mm measured maximum of the current bike, but not to the same extreme as the prototype Orbea aero race bike<\/a> we exclusively spotted on Friday.<\/p>\n

\"UnreleasedThe bottom bracket shelf is likely there to improve airflow. Ashley Quinlan \/ Our Media<\/p>\n

The bottom bracket area has a similar shelf to the Orbea on the non-drive side, which we suspect is there to improve airflow along the chainstays and improve stiffness.<\/p>\n

Also asymmetrical are the fork dropouts \u2013 on the drive side the zone is squared off to a point, while the brake side is narrower, with much of the real estate taken up by the thru-axle.<\/p>\n

\"OffsetThe fork dropouts are distinctly different from one another. Ashley Quinlan \/ Our Media<\/p>\n

No official geometry figures have been published, but the downtube doesn\u2019t feature a cutout, suggesting the front wheel could be pushed further forward than some race bikes.<\/p>\n

This effective slackening of the front end might serve to ease the handling.<\/p>\n

\"UnreleasedThis looks to be a new one-piece aero cockpit. Ashley Quinlan \/ Our Media<\/p>\n

The bike also features a new-looking cockpit. The current model has a down-kinking stem, but this one extends forward at a single angle. The tops are also notably broad.<\/p>\n

\"UnreleasedThe hidden valve still takes a little getting used to to behold. Ashley Quinlan \/ Our Media<\/p>\n

Vercher\u2019s bike is specced with a Newmen Streem A.49\/A.54 Vonoa wheelset, featuring the brand\u2019s hidden valve system. This takes the form of a smaller valve recessed inside of the rim, with access granted via an extension valve. We\u2019ll bring official details of the new Cube Litening Aero C:68X when we have them.<\/p>\n","protected":false},"excerpt":{"rendered":"Team TotalEnergies will race a new Cube Litening Aero C:68X on today\u2019s first stage of the 2026 Tour…\n","protected":false},"author":2,"featured_media":626407,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[37],"tags":[4985,101,56,54,55],"class_list":["post-626406","post","type-post","status-publish","format-standard","has-post-thumbnail","category-cycling","tag-cycling","tag-sports","tag-uk","tag-united-kingdom","tag-unitedkingdom"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/626406","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/comments?post=626406"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/626406\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media\/626407"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media?parent=626406"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/categories?post=626406"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/tags?post=626406"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
