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.

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.

Shipping costs

Consult the page "Delivery charges" for the delivery charges based on your geographical location.

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

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

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.

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.

Axxome 3 GTR - SRAM Force E1 - Prymahl Orion C35R

Après environ 200 kms au guidon de mon Axxome 3 GTR monté en SRAM Force, roue Prymahl C35R, je peux faire un retour très positif. Vélo vraiment super confortable une fois la bonne pression de pneus trouvée.Un rendement et une réactivité qui m'a bluffé car dès qu'on met des watts le vélo accélère vraiment fort et instantanément Quand on baisse le rythme on ne reste pas planté comme avec beaucoup de vélos actuels. Niveau finition rien à dire la peinture est magnifique sans aucun défaut, et les réglages sont parfaits. Bref très satisfait de mon achat

Fraxion GTR - Shimano DuraAce Di2 12v - Prymahl Orion C50 Pro

J'avais promis un témoignage après mon achat en septembre 2023. Vous trouverez en PJ, 2 photos du voyage de mon Fraxion en Andalousie (cols terribles)et sur la Costa Blanca (admirez ce trompe-l'oeil et mon petit Fraxion en bas à droite) dans le fief du vélo et des stages de pro !! Superbe machine et quel confort d'utilisation du Dura Ace DI2. Merci de tous vos conseils techniques et de votre professionnalisme.

Kit cadre Gravel Trail

⭐️⭐️⭐️⭐️⭐️ J’ai choisi le kit cadre Trail (taille L) en Viola Métallique et je ne regrette absolument pas 💜 ! Le cadre alu offre un équilibre idéal entre rigidité et confort, associé à la légèreté de la fourche carbone, le vélo est maniable, précis et agréable aussi bien pour le vélotaff que pour les sorties bikepacking bien chargées. Je redécouvre le plaisir de rouler à vélo, et c’est exactement ce que je recherchais. Merci Origine pour ce superbe vélo !

Axxome GTO - Shimano 105 Di2 12v - Prymahl Orion A30R

‌je suis très satisfait de mon Axxome GTO reçu le 07/05/2025 parcouru 1200 kms à ce jour aussi bien sur le plat qu'en montagne bonne sensation grand rouleur environ 15 à 18 milles kms l'an j'ai de bonnes sensations sur ce vélo ne regrette pas cet acquisition.

Axxome GTR - Shimano Ultegra Di2 - Prymahl Orion C35 Pro

Je possède depuis février un AXXOME 3 GTR équipé avec le groupe Shimano Ultégra di2 et les roues C35 Pro et je prends énormément de plaisir à rouler avec. J'ai changé pour remplacer mon "vieux" Look 586 de 2014 et je suis bluffé par l'évolution. Je trouve l'axxome hyper réactif. Je l'utilise en parcours vallonné voir montagneux et je fais environ 4000 kms par an. A ceux qui hésitent, foncez, vous ne le regretterez pas. Et le service client ORIGIN au top !

Axxome GTR - Shimano Ultegra Di2 - Prymahl Orion C35 Pro

Délais respectés. Qualité, emballage et livraison Top. Après 1000 km et 16500 de D+, Réactif, Efficace et Confortable. Conforme à mes attentes, heureux de mon choix.

Axxome III GTR - Shimano Ultegra Di2 12v - Prymahl Orion C35 Pro

Acquisition du Axxome 3 GTR en remplacement de son prédécesseur, magnifique vélo... tant esthétiquement que pour les sensations sur la route. Confortable même sur chaussées dégradées, rigide mais pas trop, l'Axxome est le compromis idéal sur tous les terrains et le groupe Dura ace di2 est un régal d'utilisation et de fluidité. Le vélo a subi un très bon coup de modernité par rapport à l'ancien, les petits défauts sont gommés avec succès, c'est un réel plaisir et fierté de rouler avec une telle machine ! Merci Origine !

Axxome III GTO - Shimano Ultegra Di2 12v - Prymahl Orion C35 R

Axxome GTR - Sram Force 12v AXS - Shimano Orion C35 Pro

Axxome gtr, super vélo a la fois confortable et dynamique. J’avais un peu peur de la rigidité venant d’un vélo confort, mais 160kms avec ne pose aucun problème. Dès que l’on appuie le vélo repart. J’adore le compromis confort/rendement. De plus la customisation accessoire peinture est top. Un vélo sur mesure, merci originale 👍👍👍👍👍😃😃😃😃😃

Axxome GTO - Shimano Ultegra Di2 - Prymahl Orion C35 R

Très bon vélo, réactif. Reste à l essayer en montagne et voir son comportement en descente.

Fraxion GTR - Shimano Ultegra Di2 - Prymahl Orion C50 Pro

Dompté après plusieurs sorties, vélo très agréable à faible vitesse comme à grande vitesse.

Fraxion GTR - Shimano Ultegra Di2 - Prymahl Orion C35 Pro

J’ai acheté 2 vélos Orgine le jour des portes ouvertes avec visite de l’usine. L’expérience était intéressante et motivante. Les conseils sur la configuration des vélos m’ont étés très utiles. Le Fraxion est très sportif par rapport à mon ancien vélo tout en restant agréable. Le Graxx est complémentaire au Fraxion et me permet des sorties plus audacieuses et imprévues. Je vais l’utiliser pour mon périple en bikepacking en Corse début juin .

Axxome GTR - Sram Red AXS - Prymahl Orion C50 Pro

Très léger, allie performances et confort même sur les longues distances. Plus de problèmes aux genoux et dos. Le meilleur vélo que j’ai possédé.

Fraxion GTR - Sram Froce AXS - Fulcrum

Tout simplement super, vélo réactif et malgré tout très confortable

Axxome III GTO - Shimano Ultegra Di2 12v - Prymahl Orion C35 R

Vélo reçu quasi dans les délais. A part un petit souci de pneus qui n'étaient pas ceux commandés ( mais origine m'en a renvoyé 2 après contrôle photo, parfait ) le vélo est superbe. peinture de belle facture. Après 4500 kms depuis 6 mois, je pensais que le GTO allait être un peu pataud. En plus d'être très confortable, il est très réactif ( Comment doit être le GTR ! ). Vraiment très satisfait de mon acquisition. Que ce soit avant ou après l'acquisition, Origine s'est montré très pro et accueillant. Merci.
