The answers to your questions

Tips before purchasing

Choosing a bike depends first and foremost on how you ride, your favourite terrain, your riding position and your expectations in terms of comfort and performance.

To help you, the Origine Bike Finder asks you a few questions about your cycling habits and preferences. It then guides you towards the models best suited to your needs.

If you’d like some guidance with your choice, you can also speak to a technical adviser by telephone, via video call or in person at the Rouvignies factory: Book an appointment.
The Gravel is designed for more versatile use. Its geometry and build options mean it can be ridden on both roads and trails.

It also offers greater options for carrying luggage, making it suitable for travel, bikepacking and ultra-distance riding.
All Origine models are designed to be used by both women and men. The entire Origine range is therefore unisex.

In fact, our approach is based on bespoke customisation rather than a specific range. You can adjust many aspects of your bike to suit your body shape: frame size, stem length, handlebar width, crank length, saddle setback and handlebar height.
Carbon fibre generally helps to reduce weight and improve vibration damping. It is particularly suitable when performance and comfort are the top priorities.

Aluminium offers a robust and durable solution, particularly suited to versatile use and travel.

The choice therefore depends above all on how you use your bike, your priorities and your budget.
A bike that’s tailored to your body shape is essential for your comfort, riding enjoyment and performance.

There are several ways to set your bike up:

1/ You already know your settings
You can choose the frame size, stem length, handlebar width, handlebar height, crank length and saddle width.

2/ You’d like some guidance
Our Size Calculator will recommend the frame size and key components based on a few simple measurements.
You can also select the ‘Choose sizes later’ option when placing your order. A technical adviser will contact you within 48 working hours to assist you.

3/ You already have a posture analysis
Please also select ‘Choose sizes later’, then send us your posture analysis or the settings for your current bike. We’ll adjust your configuration accordingly.
You can send your posture assessment to our team at: conseils@origine-cycles.com.

Our technical advisers will be able to take your measurements into account to tailor your setup.
The Sport position is designed for regular cyclists and those looking for a more aerodynamic position. The recommended handlebar height is lower.

The Comfort position favours a more upright riding position, particularly for occasional cyclists or those cycling long distances.
As a guide, Origine recommends:
  • under 1.70 m: 170 mm
  • from 1.70 m to 1.85 m: 172.5 mm
  • over 1.85 m: 175 mm
These figures are general recommendations. The appropriate length may also depend on your body type and how you use the product.
Origine does not offer non-standard geometry.

However, you can adjust a number of components to suit your body shape: handlebars, stem, seatpost, saddle, crankset and head tube height.
In accordance with the technical specifications set out in the FAQ, the bikes are designed and guaranteed for a maximum rider weight of 110 kg, including equipment.
The weight shown in the configurator is based on a size S frame.

You should allow for an extra 75 g per size.
Using the configurator, build your bike and then click ‘Save’.

Enter your email address to receive a copy of your configuration.
Log in to your customer portal and go to the My settings section.
No, a complete Origine bike comes with all the components required for it to function properly and safely.

Only the saddle and pedals may be missing from the order.
With the ‘Colour on Demand’ option, you can specify a RAL code or an automotive paint code in the comments section of your order.

Certain finishes, such as chrome or glitter finishes, cannot be produced.
Your bike’s suspension is preset at the factory based on the weight you provided when you created your account.
It is possible to use a trailer with the Gravel Origine models, provided they have compatible axles.

As the Graxx and Trail are lightweight bikes, however, you should take the total load being carried into account.
Only Direct Drive indoor trainers with an integrated cassette and roller models that do not block the wheel axles are permitted.

Models fitted with a clamp, a screw or which exert external pressure on the frame are prohibited.

Only road bikes and gravel bikes are compatible. Mountain bikes and e-bikes are not.

When using the trainer, avoid standing on the pedals and protect the frame from sweat splashes.
Support schemes may vary depending on your region.

We recommend that you check the applicable conditions with your local authority or the relevant public service.
In Europe, electric assistance is limited to 25 km/h.

The motor automatically cuts off assistance when you exceed 25 km/h. You can continue to pedal and ride at a higher speed, but without electric assistance.
Outlet bikes are brand-new bikes, sourced mainly from customer returns or clearance stock.

Théorème GTR M1

3 031 € | 10.8 kg
Théorème GTR M1 | Origine XC Hardtrail | Custom build

Configure and customise your bike.

Our proprietary configurator gives you the possibility to define for yourself the equipment and the deco of your bike, without any additional cost.

It's very simple, each time you change the drivetrain, wheelset and components, as per your liking, the photo, technical data sheet, bike weight and price are automatically updated. Make your dream bike lighter, more comfortable, choose the gearing options that will allow you to conquer any pass, paint it fluorescent green, or fluorescent whatever…

Let your personality and your criteria speak for themselves, you can't go wrong: our configurator will not allow you to associate components that are incompatible with each other and/or the frame. And if you are still unsure, just call us on +33 (0)3 27 88 10 10 to discuss your build with one of our technical or sales advisers.

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

No more brake hoses banging against each other as you go over a scree, no more tree branches catching the bike and rider by the derailleur hoses. Where some might see this as an aesthetic advantage, we see integration as the solution to increasing the reliability and longevity of cables and hoses, well protected in the frame.

While developing this new platform, we also integrated the saddle clamp. Here too, this provides additional natural rigidity at the top tube/seat tube junction, reinforcing the frame's strength without any superfluous weight.
Steering lock

Steering lock

We used our in-house steering lock technology. To ensure safety for both rider and equipment, the steering has a maximum angle of rotation of 72° on each side. There's no chance of ripping the sheaths or hitting the handlebar end in the event of a fall.

This technology also eliminates the curvature at the top of the downtube, providing additional rigidity and even greater performance.
UDH compatibility

UDH compatibility

Theorem has been designed to meet today's standards. The UDH, the universal derailleur hanger, allows you to protect your frame, while being inexpensive and easy to find. This format is also compatible with direct-mount derailleurs, with no intermediate bracket. So you have access to the best the market has to offer.
GTO and GTR slips

GTO and GTR slips

One frame, two behaviors.

The GTO delivers the perfect mix of comfort, vibration absorption and performance. The result is an ultra-versatile MTB, from club outings to marathon XC and ultradistance. Whatever the discipline, GTO draping limits fatigue generation and allows you to push harder.

The GTR is uncompromising on performance. Light, responsive, everything you'd expect from a competition bike. But it wouldn't be an Origine if we hadn't gone to great lengths to keep it forgiving. So it remains accessible to all, and will push you to give your all in every situation.
Hand-painted in our workshops

Hand-painted in our workshops

Origine frames are painted in our workshops in northern France.

We have chosen to use only automotive-grade water-soluble paints.

Its resistance to impact and abrasion is far superior to that of frames painted in Asia, and its ecological impact is greatly reduced.

The Theorem is available as a single frame or as a complete bike.

It comes with a lifetime warranty and is fully customizable in the Configurator to match the tastes and expectations of all enthusiasts.
