Frequently asked questions

This is a fairly common question. On each frame model page you'll find its price and what's included in the kit.

The price of a fully custom bicycle can vary considerably, especially when we move away from the conventional, since as the name suggests, it is fully customisable, allowing you to add any extras you'd like.

Whatever works for you. Need it to be simpler? I offer three options, all designed with you in mind, to make sure the final adjustments are dialled in to the smallest detail:

1. You can come and collect it from my workshop. We head out for a ride together, assess how it feels, make any necessary adjustments, and discuss details and anything that could be improved. Then we relax with a beer, chat and enjoy the moment.
2. I bring it to you. We can still ride together, though we lose the chance to make final adjustments back at the workshop and keep testing. But of course, the beer and the enjoyment aren't going anywhere.
3. I pack it up and ship it to you. You'll just need to take it out of the box, fit the pedals and take care of a few minor details. It'll be ready to ride and enjoy straight away.

What more could you need?

It's up to you. Whenever it is feasible, we'll do it. This option gives us the chance to look at your specific needs: your current riding position, your abilities, your skills and everything I've learned over the years in this field.

Think of this as an invaluable gift that very few people offer.

Where would you like to ride? That is up to you: your area or mine. During that weekend dedicated to the bicycle, we'll start shaping the experience together. It will be something special, built around how you ride.

For me, jig-based bike fitting is essential when buying a custom bicycle. It lets you achieve a perfect, millimetre-precise fit to your anatomy, both in the frame geometry and in the choice of handlebar, stem and seatpost.

The stem plays a crucial role in how the bicycle behaves. Its dimensions, together with those of the frame, determine comfort, efficiency and aerodynamics. In this blog post, how stem dimensions affect a bicycle, I explain this topic in more detail.

In the building process section, I explain bike fitting in more detail and how I integrate it into creating your custom bicycle.

Steel makes it possible to build any type of bicycle.

Steel road bicycles, steel mountain bicycles, steel track bicycles, steel fixie bicycles, steel BMX bicycles, steel gravel bicycles, steel touring bicycles, steel randonneur bicycles, and any other model you can imagine.

At the same time, within that whole range there are endless options for customisation.

Yes. However, to design the geometry, I need the dimensions of the fork you plan to fit.

Yes, that's a perfectly viable option. However, I may need you to provide some of your components during the building process so I can carry out the relevant checks. This will help us avoid complications and problems later on.

Although I have some components available for these checks during the build, not all of them have the same dimensions. Manufacturers don't always provide enough information to guarantee a perfect fit. For that reason, your collaboration will be essential to achieve the best result.

Absolutely, you can choose what best suits your needs. More or less stiff, more or less reactive, more or less agile… anything you can imagine.

Thanks to technological innovations applied to steel tubing, incredibly thin wall thicknesses have been achieved without sacrificing any strength. Beyond these thicknesses, double and triple butting is used to guarantee optimal tube behaviour, together with a significant reduction in weight.

We also have tubes with specific shapes, allowing greater customisation when looking for the right configuration.

High-end bicycle steel has undergone a remarkable evolution in recent decades, with butted tubes achieving extremely thin wall thicknesses. Thanks to new technologies, we can build custom frames adapted to your flexibility, body measurements and abilities.

Steel offers countless advantages:

• Durability: it does not accumulate fatigue through normal use and has high impact resistance, which gives it strong long-term reliability.
• Comfort: it absorbs road vibrations more effectively, providing a smoother and more pleasant ride.

More than just a bicycle, a custom steel bicycle becomes an extension of your body, a perfect symbiosis between you and the machine.

Each material has features and advantages that make it stand out from the others. That's why I'll always say the same thing: no material is inherently superior to the others.

For example, fitting a carbon fork on a custom steel frame can provide greater comfort thanks to its better absorption of road irregularities. However, it can feel stiffer compared to a steel fork, which affects the response and handling of the bicycle.

On the other hand, a steel fork can make the bicycle easier to handle and offer more options for adding accessories, such as extra bottle cage mounts. However, it may not absorb road irregularities as well.

Confusing, right? Forget all that. Once we talk and understand what type of bicycle you need, the choice of fork will become obvious on its own.

A difficult answer, because as always, there is an 'it depends'. Manufacturers are pushing disc brakes in their catalogues and every day it is harder to find road bicycles with rim brakes or wheels compatible with this type of brake.

Broadly speaking: rim brakes are lighter, simpler to maintain and cheaper, but lose power in the wet and on long descents. Disc brakes offer much more power, better modulation and consistent performance in any condition, but they make the bicycle more expensive and the setup is more delicate.

If you have doubts about which suits you best, email me and we'll talk it through calmly.

Currently, all my bicycles are built around the threaded T47 standard. This standard is compatible with all current axle systems and gives the frame additional features, such as increased stiffness in an area that is crucial for performance and comfort. There is also the option to work with a threaded BSA bottom bracket.

I don't use Press-Fit or BB30 systems because of the issues they tend to create.

I mainly work with Deda steel, under a special edition created for OXIA, though I also use tubing from Columbus. Both are currently considered leading brands in bicycle tube manufacturing, alongside Reynolds and Tange.

Columbus and Deda offer a wide range of series and tube types in their catalogue, designed to achieve high performance in bicycles. These tubes include specific shapes, butting and very thin wall thicknesses that deliver a strong weight-to-strength ratio.

Sometimes I focus exclusively on one brand, while in other cases I combine different brands, all depending on the specific needs and characteristics of each frame.

Yes, everything is made by hand. Every tube cut and joint is worked meticulously by hand with a file, taking care of every detail. The other finishes are worked with sandpaper and a scouring pad, and in some cases specific tools are used to achieve tight tolerances and precise fits. For brazing, I use the fillet brazing method with brass and silver rod.

Building steel frames with this method is characterised by preserving the material's properties during brazing. The joints are polished and worked by hand to achieve a clean finish, where the joint between the tubes cannot be seen.

The whole process is under my control, from the initial design to the final assembly. The only exception is the paintwork, which is done by a workshop specialising in steel bicycles, though I supervise every step to ensure the right standard.

Here is the complete process:

I have 20 years of experience as a bicycle mechanic, including World Cup races, Olympics and Titan Desert. Your bicycle will be carefully assembled, ensuring an outstanding setup tailored to your biomechanics and intended use.

The frames are painted by a workshop specialising in bicycle paintwork.

The OXIA team includes an art director specialising in cycling. During an initial interview with the client, this professional gathers their ideas and preferences, then puts together a fully custom design.

We use high-quality water-based paint, which produces excellent finishes and supports environmental sustainability. Before starting the painting process, together with the designer, you'll carry out several brainstorming sessions to choose the right colours, reflecting the personality and details that will give the frame its distinctive look and feel.

Yes, as long as you have a clear idea of your bicycle's design, we can deduct the cost of the design work from the total price. The design work has a value of 180€.

However, it's crucial to bear in mind that the painter needs a detailed design or sketch to work from on the bicycle; we can't leave anything to improvisation. Since the painting process is highly complex, it's essential to have every detail well defined before starting.

Beyond that, it is worth considering whether it really makes sense to skip investing in the design. Design work where the designer has freedom and room to apply their creativity tends to produce striking, more considered results.
