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.

We guarantee you a bike that is perfectly adapted to your size

- Not fully satisfied?

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

Use either a bank card or bank transfer to pay for your Origine bike.
If French resident you can also pay by cheque in up to 3 interest-free instalments.

Customise your bike

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 FS 120

For riders seeking adrenaline, we've prepared a sensation-packed machine with the 120mm version. Explosive, agile, and playful, it's the bike redefining the basics of downcountry. Reduce the SAG, close the compressions, and it turns back into a World Cup contender.

Dynamic Linkage

When developing the Théorème FS, we made suspension performance our number one criterion.
We considered all the parameters and effects of full-suspension to reach our final choice. We required a system that was light, and highly efficient in tough technical sections, and that gave the sharpest handling. The solution was evident:
A Flex Pivot system, in other words, a deformable parallelogram, where the rear pivot point is provided by the deformation of the seat stays. Following on from Dynamic Response on our road bikes, discover Dynamic Linkage on our mountain bikes.

Integration

We’ve gone for maximum integration. If integration is more associated with road bikes, we wanted to better protect all the cables by placing them inside the frame. We wanted to eliminate as much as possible all the white noise when riding. Riding the Théorème FS, you will only hear your breathing and the tyres crunching along the trail.

Integrated steering lock

Why limit ourselves to integration when we can develop an entirely new headtube?
A revolutionary head tube. Why limit ourselves to integration when we can develop a completely new head tube? Thanks to an integrated lock developed by our engineers, we've limited the head tube angle to 72°.

Full UDH compatibility

From the very beginning of the development of the Théorème FS, we designed it to adapt to the latest standards.
The UDH universal derailleur hanger, lets you inexpensively protect your frame. This format is also compatible with direct-mount derailleurs, with no hanger. With the new Théorème FS you can access all the new standards in MTB bikes.

Théorème GT - Shimano XT - Fulcrum Red zone 500

Peut-être le premier origine à faire et finir la tour divide aux US

Thèorème GTR - SRAM XX1 Eagle AXS - Polaris C25 pro

VTT semi rigide GTR full carbon. Après 3 mois de sortie Super vélo ,sensation XXL, dérailleur SRAM XX1 Eagle AXS , roues Polaris C25 pro. Suite à un petit souci lors d'une sortie appel au SAV réactivité max . Je recommande. Denis

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" - Fourche Rock Shox Sid Select 100mm - Shimano XT M8100 - Roues DT Swiss XR 1700 Spline

Bonjour, Après que mon cadre carbone Merida 26’´ ait rendu l’âme, me voici en possession d’un magnifique Théorème GT rouge flamme, full XT, roues DT 1700: aucun regret! Le 29’´ est une révélation et le vélo est à la fois très confortable et malgré tout joueur, plus que je ne l’imaginais. Je n’ai eu aucun problème avec le service d’Origine , que ce soit en amont de la commande où mes questions ont toutes trouvées réponses et par la suite avec un délai respecté et une livraison sans encombre.

Théorème GT - Shimano SLX - Roues Shimano XT

VTT très facile à piloter, maniable et très agréable. Confort relativement bon pour un semi-rigide, malgré le carbone. Très satisfait de mon choix ; dispo conforme aux prévisions. Très content de mes choix et aucun regret sur la couleur (Orange Shakir). Réception du VTT à l'usine directement ; réglage précis sur place. Vraiment top comme expérience je recommande.

Théorème GT - Shimano XT - Roues Prymahl Polaris C25 Pro

Passé les 500 km et toujours très satisfait de mon théorème GT avec jantes Prymahl. J'ai quitté mon ancienne monture carbone 2x10 pour ce vtt. Pas déçu de l'accueil, du conseil et du suivi de Origine. Montage fourche Rock shox Sid 100mm, transmission shimano XT, pédalier slx et freins Shimano Slx.

J'ai acheté mon vtt en début d'année j'ai déjà fait 1000 km et 20 000 mètres de dénivelé exclusivement en chemin forestier et single, un vrai bonheur, j'ai eu vite fait d'oublier mon Specialized Epic carbon tout suspendu !!! vraiment une bête de course et également très confortable pour un semi rigide. Très heureux de mon achat je le recommande sans retenue merci à Origine !!!

Axxome II GTR - Théorème GT

Fier de mes « Origine » Un an après un Axxome GTR, je viens de faire l’acquisition d’un Théorème GT. C’est dire combien je suis satisfait. Et l’accueil à l’usine toujours très agréable et riche en conseils. Bravo à toute l’équipe.

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.
