Principia

Born from triathlon in 1990, Principia innovates with light, stiff aluminium frames. High-performance road, tri and MTB.

In 1990, three triathlon fanatics set up a workshop in Denmark with one obsession: a frame that passes on every single watt without wasting it. Tired of bikes without temperament, they tamed aluminium and placed their brand under the patronage of Isaac Newton. At Principia, stiffness is not a marketing argument, it’s a design principle.

This Scandinavian rigour speaks first to cyclists looking for efficiency: those who judge a bike by how it accelerates and behaves when the pace rises. On the road as on a fast gravel bike, the frame makes every acceleration sharper. Nothing superfluous, neither in the lines nor in the handling.

Welcoming Principia came naturally to the lovers of fine mechanics that we are. Aiming for the hills of Brabant or a first triathlon? Our team points you to the right geometry and groupset. As a gravel and road bike shop in Brussels, we admit a soft spot for this Danish school that prefers precision to showing off.
