Note
Our products are in constant development, which is why it is possible that the current models already have differences and improvements compared to the ones you have seen as an example in the photographs on the page.
WHY A CAMPMAJÓ TANDEM?
Our aluminum gravel tandems are known for their combination of strength and lightness, resulting in an agile and high-performance tandem. Thanks to their stiffness and responsiveness, our aluminum tandems will allow you to reach high speeds and enjoy a smooth and efficient driving experience both on roads and gravel tracks.
The trust placed in our brand by elite cyclists evidences the exceptional quality and performance of our gravel tandems. Our dedication to innovation and constant improvement drives us to continue to lead this sector.
Moreover, now with the electric component, you will have extra energy to cover longer distances without worrying about fatigue. Opening up new possibilities for exploration and adventure, allowing you to discover new and challenging places that previously might have been inaccessible.
Join the community of passionate cyclists and experience the thrill of hitting roads and gravel tracks on a tandem made just for you.
EXTERNAL DRIVETRAIN SYSTEM
Our tandems are equipped with an external transmission system, of our own design. In this system, the primary 1:1 transmission is built externaly. This way we avoid the most common chain problems in conventional tandems.
To be able to mount this system, we mount SunRace MX 94mm bcd cranks on the most affordable tandems.
If you want to mount higher end cranks and maintain the correct chain line, we make our own spiders. This is why we always mount “direct mount” connecting cranks.
You can see an example of these in our road tandems.
REAR SPIDER
With the rear spider we manage to unify the two plates with the connecting crank. The outer plate is fixed with a 1:1 ratio with the front plate. The largest chainring is the one that acts as a single chainring and is responsible for transmitting the pedaling force to the rear wheel.
CHAIN TENSIONER
Our tandems carry our own tensioning system consisting of an Anchorage ISCG05 tensioner with an 11T jocker wheel. This system is much more practical than the conventional eccentric system.
1 – Easier to adjust, no need to remove the cranks
2 – You can tighten the chain without changing the geometry
3 – By tensioning upwards, the chain is more protected
4 – Easier to find the right tension
At Campmajó we have been developing our own chain tensioner for years and it works amazing! Even for our competition models.
ADJUSTABLE REAR STEM
Per assegurar la màxima comoditat del copilot, per als nostres tàndems fabriquem la nostra pròpia potència posterior ajustable. En aquest sistema la mateixa abraçadora de la potència és la que fixa la tija del sellent davanter. D’aquesta manera es pot ajustar l’alçada del sellent sense que la potència canvii de posició. La posició del manillar s’ajusta amb el propi sistema graduable de la potència.
Aquest sistema resulta molt còmode en general, però especialment quan es tracta d’un tàndem que canvia de pilots habitualment.
