Performance and comfort


Versatile hardtail frameset

For fast, and longer rides, whatever your level, the Théorème GTO frame kit is the carbon hardtail that's perfect for you.
Featuring high-modulus fibres and the expertise of our engineers, it's as comfortable as it is performing, allowing you to push back the limits of hardtails.

100% customisable online, build it to your image, ride style and budget, with for example, a 120mm fork or a dropper.

Technological benefits

Theoreme Hardtail

Theoreme Hardtail

Discover the new Théorème hardtail, a concentrated powerhouse that highlights speed and performance. And as is always the case at Origine, these features are not at odds with comfort and accessibility - quite the contrary.

The technologies we have developed make our hardtail one of the lightest and best performing in the highly-competitive world of XC.
Dynamic Response

Dynamic Response

The Dynamic Response concept reflects Origine’s personality to obtain the very highest performance, while maintaining a certain level of comfort. The choice and lay up of carbon fibres have been designed to give priority to response over stiffness and to allow extremely rapid return after deformation.
Our engineers focused the bike’s build around the Dynamic Response concept. Rather than preventing the frame from deforming at various stress points (bottom bracket and the head tube when cornering) so as not to lose power transfer, the Théorème works more like a spring, an archer's bow for an extremely fast return following deformation.
As a result, it's more responsive, more predictable, even in series of fast, tight bends. It is also easier to steer and more comfortable on long rides, during those moments of tiredness or in winding, technical areas.
Integration

Integration

Say goodbye to brake hoses banging against each other as you ride across a scree slope, say goodbye to a branch catching the bike and rider by the derailleur cable. Where some people might see this as an aesthetic advantage, we see integration as the solution to increase reliability and longevity of cables and hoses, all well protected inside the frame.

But we didn’t stop there. We took advantage of this new platform to integrate the saddle clamp. This has added more strength to the frame by reinforcing the top tube/seat tube junction, without adding any extra weight.
Steering limiter

Steering limiter

We have featured our in-house designed steering range stop. To improve rider and equipment safety, the bar’s rotation is limited to a maximum 72° angle either side. This prevents the bar, in the event of a crash, from over-rotating which could damage the frame and hoses, or possibly injure the rider from contact with the bar ends.

It also means that we can apply the same technologies that have proven so successful on the Théorème FS, such as a entirely straight down tube from the bottom bracket to the head tube for added stiffness and precise, responsive steering.
UDH hangar compatible

UDH hangar compatible

First seen on our Théorème FS, we have retained compatibility with UDH derailleur hangers on our Théorème hardtail. The main advantage of UDH hangers is the ease with which they can be replaced either at home or on the road. They are also compatible with direct-mount derailleurs without the need for an adaptor.So you have access to the best technologies on the market.

GTO & GTR carbon layups

GTO & GTR carbon layups

One frame, two different styles.
The GTO provides the perfect mix of comfort, buzz filtration and performance for an extremely versatile mountain bike, for use on club rides to marathon XC and ultra-distance. Whatever the discipline, the GTO carbon layup cuts fatigue and lets you keep pushing harder.

The GTR is uncompromising on performance. Light, responsive, everything you'd expect from a high-end racing bike. But it wouldn't be an Origine if we hadn't made every effort to keep a certain tolerance. Accessible to everyone, it will still push you to give it your all in every situation.
Hand-painted in our factory

Hand-painted in our factory

Origine frames are painted in our workshops in northern France.
We only use automotive-grade water-soluble paints as their resistance to impact and abrasion is far superior to that of frames painted in Asia, and their ecological impact is far less.
Available as a frameset or as a complete bike.
As with every Origine frame is benefits from a lifetime warranty and using our Configurator you can custom build your Théorème to your taste, style of riding and budget.
