The answers to your questions

Where (and how) to maintain your Origine bike

Origine offers you a wide choice of maintenance and repair options for your bike.

With several options now available, you are free to choose the service that best suits you and your pocket, such as Origine-approved bike mechanics, some of whom will even come to your home, alternatively nothing to stop you using your usual LBS (Local Bike Shop); you can also drop your bike off at our factory and we'll repair it for you (following quote), or why not maintain and fettle your bike yourself using our Origine tutorials.

Warranty

- What are our warranty terms?

At Origine, we believe that an exceptional bike deserves an exceptional warranty.
Therefore, each model comes with a lifetime warranty on the frame and a 2-year warranty on the components.

The warranty is managed directly in our factory by our teams. Your point of contact is an expert who will be able to give you an answer or an explanation, decide to send you a component or plan repairs or other work for your bike.

You can find all the information on this subject on the "Warranties" page.

You have 14 days following the reception of your order to change your mind and withdraw.
Send us your request by e-mail or registered letter with signed receipt addressed to our head office, providing your contact details and invoice number.

Returned products must be new, complete and in their original packaging.
This guarantee does not apply to specially designed products, i.e., those not found on our website.
Please refer to our General Terms and Conditions of Sale for more details on the terms of this clause.

If having a bike that fits your image is important to many cyclists, it is also vital that the bike also fits you and that you are well positioned on it. Yet many people neglect this point and irrespective if a novice or a seasoned racer the position on the bike is the guarantee of your comfort and your performance.

When finalising the configuration of an Origine bike, there are several options when choosing the position on your bike.

1- You know what you want:
Choose the frame size, stem length, handlebar width, cockpit height, crank length, and a saddle of the appropriate width. We leave the choice to you.

2- Use our Size Calculator
With just a few, easily determined measurements, it defines the exact dimensions of each component for a bike that will fit you perfectly.

How do you take your own measurements at home?
Watch the explanatory video on our YouTube channel to learn how: https://youtu.be/5HdPZWSQWqA?si=6CTwsw0ndrZPvZUS

3- You need some help from our advisors
Validate your order by clicking on "Choose sizes later", one of our technical advisers will call you back within 48 hours.

4- You have a recent bike fit or wish to replicate the settings of your current bike
Select the option "Choose the sizes later" and send us the measurements by email; we will build your bike according to them.

Whatever your choice, one of our technical advisors will systematically call all customers to check measurements before we start production of your bike.

RIGHT SIZE GUARANTEE
All our bikes come with a 1-month CORRECT SIZE GUARANTEE.
If you are not completely satisfied with your position after your initial rides, we will, free of charge, change the bike’s component sizes within one month of delivery of your bike.
See our guarantee conditions here (Link to the Perfect Fit page).

Good to know:
This service is available in all cases, even if you have decided to choose frame and component sizes without using our size calculator.

Women's bikes

At Origine, our policy has never been, and never will be, to produce scaled-down men's bikes for women.
Our guarantee to produce a bike that is perfectly adapted to your size applies equally to women as it does to men. In choosing from 6 different frame sizes, 8 different stem lengths, 3 different crank lengths, a choice of 2 saddle layback options, and more than 10 different stack heights, we can create the perfect combination that corresponds perfectly to your body shape.
And this is possible across the whole range. At Origine, women have just as many choices as men.

Further info

How do we ship your Origine bike to you?

Origine bikes are shipped fully assembled and adjusted, you just need to fit the front wheel, the bar (MTB only) and adjust the saddle height.

Then you are good to go.

Find all the information and how we ship on the delivery page.

How to configure your bike

Fully configure your bike to your image and adapt it to your riding style, expectations, budget and body shape and size.

Firstly, start by choosing the model of bike that interests you and add the components that you want including everything from the make and model of drivetrain, the tyres, the frame colour and the saddle type.

With each component choice the visual, technical data sheet, bike weight and total price are automatically updated.
Let your personality and expectations speak for themselves, you can't go wrong as our configurator will not allow you to select components that are not compatible with each other.

Further info

I want a colour or decor that are not found in the configurator

Colour:
We believe that a bike that reflects you should do so completely and using our Colors On Demand® custom app you can find the colour scheme THAT YOU WANT.

When finalising your order, simply indicate in the "Comments" box a RAL colour chart number or the reference of any car manufacturer's colour scheme.

Good to know:
- We are not equipped to produce chrome or glitter tints, and unfortunately it is not technically possible to create a computer-generated of the bike with a custom colour scheme.

- The boundary between two colour areas cannot be changed as this requires time-consuming adjustments that cannot be made for a single bike.

Decor:
- For technical reasons, it is not possible to select other decors than those found on our configurator. It is not possible to customise the colour, change the position, add or remove them, or mix them with those of other models than the one initially selected.

Further info

Current production lead times

Delivery time for a bike (in weeks) : 4/5
Delivery time for a frameset (in weeks) : 3

If you have chosen a component with a longer delivery time, you will be delivered within one or two weeks from that date.

These lead times are given as an indication only and only come into play once your order, including all the component size choices, has been confirmed and full payment made.
Lead times are subject to production issues and our own suppliers' lead times.
Unfortunately, our technical advisors are unable to reliably inform you of the status of your order prior to the indicated delivery date.

Payment and financing

Technological benefits

Theoreme GT

Our ambition was to come up with the design of such a formidable machine that top performance at every level would be possible.
Two and a half years of painstaking research were necessary. Two and a half years of trials, of failures and complete blank outs. Re-thought, re-designed and re-worked hundreds of times.
Pushing our know-how and technology even further and challenging ourselves to be bold, even bolder.
Why? Because we wanted an extremely responsive MTB frame, but also a comfortable frame. That is as much a player as it is reliable.
Challenge assumed!
Thanks to the Dynamic Response concept, what we have achieved is not a bike, more a partner in crime!
Like an archer's bow that instantaneously returns to its original shape upon the release of the arrow.

Dynamic Response

The Dynamic Response® concept reflects Origine's character: the perpetual search for excellence in performance, while retaining a certain comfort. The weave and layering of the carbon fibre was specifically studied to opt for a responsive frame rather than a stiff frame to enable an extremely fast return following deformation.

Our engineers developed 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.

New XRD® technology

We have also developed XRD®, a wholly new system of fixing the derailleur hangar so that it remains in the rear wheel's axis. The result is improved shifting accuracy and the wheel's stiffness in the frame is increased by 17%.

We have based our XRD® technology on Shimano's new standard thru-axle

EPS moulding technology

The EPS internal polyurethane frame moulds prevent the build-up of resin in the angles but smooth out the frame tubes’ internal surfaces.
Consequently, the frame is not weighed down by excess unnecessary resin.
Smoothing out the internal surfaces results in a consistent tube thickness, as a result the frame can better filter out ground buzz and vibration.

Toray® T800 and M40 M50 carbon fibre weave

The Japanese firm Toray® is the world's largest manufacturer of carbon fibre, its fibre is used in several fields such as car racing and the aeronautical industry. Toray fibre is used, for example, in the manufacture of the Boeing 787.

The frame is now moulded using unidirectional high modulus T800 fibre. A mix of 3K M40 and M50 fibres is used in the areas subject to strong torsional strain to as to obtain optimal performance while maintaining a certain level of comfort.

Hand-painted in our factory

All Origine frames are painted in our assembly plant in the north of France.

We have conscientiously chosen to exclusively use car industry quality water soluble paints.
Their resistance to scratches, impacts and abrasion is far superior to those frames painted in Asia and the impact on the environment is considerably less.

Théorème GT - Shimano XT - Prymahl Polaris A25 Pro

30 ans de VTT derrière moi, retour sur un semi-rigide... Des décathlons, un Zesty, un fuel EX et maintenant un Théorème GT. Mon premier carbone monoplateau. Un vrai jouet, très réactif, vif, léger, grisant ! Fourche de 120mm, tige de selle télescopique, ça passe vraiment partout et ça va vite ! Évidement ça bute sur du terrain dur et défoncé. Le manque d'un amortisseur centrale se fait sentir. Mais à plus de 50 ans, j'ai (re) trouvé une machine à sensation.

Théorème GTR - Sram 12v lunar - Prymahl Polaris A30 R

Le vtt est très agréable dans les descentes. Très réactif dans les relances. Equipé en Sram XX1 pour la transmission et avec des freins SHIMANO XTR, le vtt a un bon équipement technique. La possibilité de choisir soi-même ses composants est vraiment un plus : vtt à la carte. Je conseille fortement Origine.

Théorème GT 29

Reçu à la mi-décembre, mon Théorème GT a parcouru un peu plus de 200 km. J'apprécie sa légèreté (9,8 kg), son agilité et son confort, la fourche Sid Select 120mm Remote est vraiment magique ! Je continue à le découvrir dans les côtes et sur le plat en forêt. Très roulant, il est aussi à l'aise sur les chemins qu'en ville. A chacun de l'équiper à son usage avec les bons pneux et les bons composants mécaniques. Personnellement j'aime bien aussi l'utiliser pour aller faire les courses en ville car il est très maniable

Théorème GT 29

Après presque 25 ans avec un Vtt Merlin, je me suis décidé à acheter un nouveau vélo... C'est un théorème GT, monté XT et fourche Fox 32 Je n ai pas encore beaucoup roulé avec (j'attends le dégel), mais je ne suis pas déçu ! Les plus : le configurateur la communication la rapidité de la livraison (3 semaines) la qualité du cadre , du montage et du comportement du vélo . le confort Les moins : je cherche encore

Théorème GTR 29

Après une commande sur le configurateur origine, 2 ou 3 appels téléphoniques de votre part pour valider les mensurations, j’ai reçu mon vtt théorème GTR. Une pure merveille. Merci à toute l’équipe origine pour votre professionnalisme. Cela fait plaisir de voir que le savoir faire français existe toujours.
