IN BRIEF
Origine, the French direct-to-consumer bike maker, is launching the Fraxion X, a fully redesigned aero road bike. The brand claims an aerodynamic gain of 15 watts at 40 km/h, with stiffness up 11% at the head tube and 16% at the bottom bracket. The bare frame is quoted at 875 g in its Lite fibre version, and the bike takes tyres up to 32 mm. Two carbon grades are offered, Core and Lite, the latter saving 150 g on the frameset.
| Bare frame weight | 875 g (Lite fibre) |
| Carbon grades | Core and Lite (Lite: −150 g on the frameset) |
| Claimed aerodynamic gain | 15 watts at 40 km/h |
| Stiffness | +11% at the head tube, +16% at the bottom bracket |
| Tyre clearance | Up to 32 mm |
| Seatpost | Kammtail profile |
| Prices recorded on the official configurator (19/09/2026) | From €4,882 (M1 build) to €11,015 (M7 Aero build) |
Origine, the French brand that sells its bikes direct through a configurator, unveiled the Fraxion X on 17 September, the new generation of its aero road bike. Origine presents it as the fastest road bike it has ever developed. The brand puts precise figures on it: 15 watts saved at 40 km/h, and an 875 g bare frame.
Origine Fraxion X: 15 watts and two stiffness gains
The figure Origine puts forward is an aerodynamic gain of 15 watts at 40 km/h. The launch page does not state the point of comparison; according to BikeRadar, that gain is measured against the Fraxion GTR, the model it replaces. The brand pairs it with stiffness up 11% at the head tube and 16% at the bottom bracket — the two areas that determine steering precision and pedalling efficiency.
Going into the detail of the frame, the official spec sheet explains that the fibre work targets stiffness at the bottom bracket and the head tube for immediate power transfer, while the seatstays are tasked with controlled vertical compliance intended to limit fatigue. The redesigned seatpost adopts a Kammtail profile — that shape truncated at the rear which seeks the aerodynamic benefit of a teardrop without its length.
Two carbon grades, 875 g and tyres up to 32 mm
The Fraxion X is ordered with two carbon grades, named Core and Lite. According to Origine, the two share the same design and the same aerodynamic performance: the difference comes down to weight and character, the Lite fibre saving 150 g on the frameset and offering, the brand says, more responsiveness during accelerations, while the Core fibre prioritises, according to Origine, a slight degree of flexibility suited to long distances and Granfondo riding. It is in this version that the bare frame is quoted at 875 g.
On tyres, the spec sheet claims clearance up to 32 mm. Above the Fraxion X, Origine places the Fraxion X RR, presented as the ultimate version of the frameset, lightened with titanium components. In its top-of-the-line configuration, Origine quotes this RR at 6.60 kg, UCI-approved and intended for the teams the brand sponsors for the 2027 season.
Prices you can read in the configurator
At Origine, the bike is configured and bought on the brand’s own website. Viewed in a browser from France on 19 September, that configurator showed seven complete Fraxion X builds, from the M1 at €4,882 to the M7 Aero at €11,015. These amounts correspond to the default configurations offered that day and vary with the options chosen. Origine also advertises the Fraxion X “from €3,900 to €11,500” on its launch page, a range that does not exactly match the default builds recorded above.
