Technological benefits

Graxx III GTR Explore

Graxx III GTR Explore

The Graxx carbon gravel bike is the epitome of performance, comfort, ease of use and durability. The Graxx in its GTR version is built for speed and performance, while retaining the comfort that characterises Origine bikes, improved with the front fork suspension.
Gravel front fork suspension

Gravel front fork suspension

The Rock Shox Rudy fork, specially designed for gravel riding, offers 40mm of travel. Preload is managed with an air cartridge (SoloAir™ technology). The damping is managed by the Charger Race Day cartridge with a lockout for rolling sections.
UML (Unique Matrix Layup)

UML (Unique Matrix Layup)

The results of months of research led us to develop a fibre moulding technique called UML for Unique Matrix Layup. The carbon sheets are assembled on the front triangle in a single operation around a single matrix. There are no joints, no excess resin, no unnecessary overlapping, just pure, flawless carbon fibre.

This new version of our internal mould allows the fibres to be compressed uniformly over the entire front triangle using pneumatic pressure.
CCT+® technology

CCT+® technology

The CCT+® (Continuous Carbon Tubing®) rear triangle further enhances these features. The chain stays and seat stays on the Graxx are connected by a single continuous carbon tube, with no hard points between the bottom bracket shell and the seat clamp. Vibration from an imperfect ride surface is spread over the entire length of this continuous tube (bases + stays) for better filtration.
Internal cable routing

Internal cable routing

Outre l’aspect visuel, l’intégration offre quelques avantages notoires surtout pour une pratique bikepacking.
Les gaines et durites ne viennent en rien contraindre la rotation du poste de pilotage. Le développement de cette intégration nous a pris des mois sur le Fraxion, nous n’allions pas nous priver pour décliner cette recette.
Grâce à cette intégration la direction est encore plus fluide qu’avec des gaines et durites apparentes qui pouvaient parfois contraindre le poste de pilotage.
Wheelset compatibility 700x45 or 650x47

Wheelset compatibility 700x45 or 650x47

The Graxx has been designed and developed to be used with 2 different wheel sizes.
The frame allows maximum widths of 700x45 and 650x47 for maximum versatility. So, you can characterise your bike as you see fit either as an infallible cross-country bike or a sharp blade for smooth roads, you decide your specifications and ride the bike that's perfect for you.
