It all begins with a talk. We will discuss how you will use your new bike, what would you like your bike to feel like, and about your experience or needs. We would love it if you could drop by our shop to meet us and to visit the workshop.
Most of our clients are from outside of Madrid and Spain, so we have plenty of experience completing the process via phone, e-mail, Skype, etc… Every custom frame/bicycle is made to measure, so the ordering process is different each time, but it can be described in the following steps:


Get in touch and talk. We start by getting to know each other and discussing your ideas: what are you will use the bike for and what you will expect from it?

Quotation. Once we both have a clear idea about your new bike, we can calculate the approximate cost. During the design stage we have room for some changes (if required), but normally this will be the final price.

Deposit. In order to ensure a place in the line, cover design expenses and buy materials, we ask for 40% of the agreed cost of the frame in advance.

If it’s a complete build, we will also need 100% of the component costs at this stage..

Taking measures or fitting. The design of the bicycle is made taking into account two different sets of measures: body measures and your current bike dimensions. The first ones will determine the general dimensions of the bicycle whilst the second set will give us an idea of your position (two people with similar body measures can have very different positions on the bike).

We will gladly get in contact with your preferred fitter if a biomechanics study is needed or desired. We have a special price for our customers at Ciclismo y Rendimiento here in Madrid.

Design. With all of your biomechanical information, we will make a design/simulation. This representation will be used during construction, but it is also a way to project how the bike will look and to get an idea about your possible position on the bicycle.

The construction. Once all of the materials and the design are waiting in the project box, the construction of the frame takes between 40-50 hours, depending of the complexity. Normally I take pictures of every build and post them in an album.

Paint. The next 15-20 days are for the paint. No frame will be finished without paint. Paint not only gives the final, completed appearance, but it is also what prevents rust. All Arregui-Velázquez frames are protected on the inside with a waxy, protective filmthat resists humidity and severe corrosive atmospheres.

Assembly. Last phase will correspond to  the proper assembly of components (in the case of a complete build). Every part has to be adjusted to match the the original design to dial in fit and function.

We prefer complete builds to ensure component compatibility. If you’d like us to fit your parts to a new frame/fork, all components (or most of them, depending on the case) must be available prior to the design phase.

The fork is an essential part of the character of the bicycle, since the rake and the shape of it will determine the overall behavior of the bicycle; the handling of the bicycle depends directly in the type of fork used. A custom fork could make an existing bicycle handle more stable or faster, or give a smoother or more aggressive ride. The type and shape of the tubes, the existence or position of the curve in the blades or rake could all alter, in one way or another, the behavior of the bicycle.

A custom stem helps us dial in one of the three points of contact you will have with your bike (your handlebar, your saddle, and your pedals). It’s very common that cyclists have to use what’s available on the market, but with a custom stem, we can change the length or rise any way we want, in order to find the best place for the handlebar.

A custom step finishes off a build aesthetically and functionally. We can make fillet brazed or lugged stems, quill or threadless, high-rise or with integrated cable stops or other accessories.
