With geometry size chosen by the rider or through a biomechanical study made by Muntané Full Balance, we can create a bike that not only adapts to your dimensions, but also to your own natural movement.


20" trial bikes with fully customizable geometry, colors and components.


Here you will find all the general characteristic specifications of our 26″ trial bikes. Remember that both the frame and its components are 100% customizable. If you want more information about other types of components that we usually mount, you can contact us and we will advise you so you choose the highest quality components according to your budget.The price of the components is added to the final price of the frame and fork.

Over the years, trial bikes have evolved a lot, but in 2021 Campmajó managed, without a doubt, to position itself at the forefront of this innovation.

Thanks to the collaboration with Muntané Full Balance, we launched the first trial prototype adapted to the rider’s body and movement. The Trial World Champion 26”, Sergi Llongueras. Now, after 3 years of testing and refinement, we want to make this concept accessible to everyone and bring health to the trial world.



Muntané Full Balance is an innovative and patented geometry system that seeks to find harmony between the movement of the rider and the bike, allowing each rider to enjoy their own natural movement without accumulating stiffness and harmful tensions for the body in the long term. A geometry that allows you to reach maximum performance through health and well-being.

The main differences between an MFB geometry and what we currently find on the market are the following:

We work with shorter reaches and longer stems

This allows us to delay the turning point of the bike, making it more in line with the body’s natural turning point, the abdomen. We are used to going with long reaches, a longer reach of the account can cause tension and pain in the back, neck and ribcage.

Smaller head tube angles and increased fork offset

This adjustment allows us to achieve a much more agile and natural interaction between frame and fork, making the transmission of movement between feet and hands more fluid and without interruptions. In this way, the small gestures to hold the balance are much easier and more pleasant for the rider.


From Campmajó we have verified that this system allows us to make trial a much healthier, fun and accessible sport. We want the maximum number of people to be able to enjoy it, which is why we have created two different levels of customization:


Through a biomechanical study, we find the ideal geometry for your body dimensions and your natural movement. This is the option we recommend the most, especially if you are a pilot who is dedicated to competition or have some kind of pain or physical pathology.

  • Price includes face-to-face measurement session (Sant Cugat del Vallès, Spain)
  • Custom geometry design (MFB system)
  • Frame and suspension plate manufacturing
  • Frame painting (1 frame colour + 1 logo colour)
  • Stem, handlebar and seat measurement and placement
  • Assembly of components (if chosen by the customer)

While it will always be better to have a bike made just for you, from an MFB geometry we have created four possible standard sizes to be able to approximate the most suitable geometry for each customer without the need for a biomechanical study.

This is the best choice for growing young riders and people who want a healthier trials bike for spontaneous training

We are a fully independent bike manufacturer, meaning we do not rely on any other outside company to manufacture our frames and forks. Our bikes are 100% manufactured in Catalonia.

We shape the tubes ourselves, design and manufacture the machined parts of the bikes and weld the frames together one by one. The fact of producing bicycles by hand means that we can adapt each bicycle to the customer’s taste, but it also gives added value to our product, since each bicycle is unique and has been created with great care, taking care of even the smallest detail.

In addition, the creation process becomes a unique experience for the customer, since he participates in the design of every detail of his bike, as well as being able to track and see all the steps we take during the manufacturing process .


Sergi has been a rider for Campmajó Bikes since 2020, when in collaboration with Muntané Full Balance we designed a custom bike adapted to his movement and his body to be able to cure the pain in his knee that he had been suffering for years.

For this project, Sergi needed a bicycle brand that, following his vision, was able to produce new and innovative prototypes and accompany him in the development of a bicycle concept that has not yet been done before in the world of the trial.

“Campmajó RISE has allowed me to see sport, even at the highest level, as synonymous with health and constant improvement” – Sergi Llongueras for Bike magazine.

The one in the picture is the first version of his current bike. This bike has an innovative geometry in the world of trials with a very short reach, great fork throw and very long power. All the necessary requirements to adapt it to your body and natural movement.


In this video you can see one of Sergi Llongueras’ training sessions with the RISE campmajó, the prototype prior to the Abu Dhabi edition, at his famous training park in Orrius, a few months before he leaves for the world championships in Abu Dhabi 2022.
