Technology

Traditional frame design uses tubing with identical diameters and wall thicknesses for all frame sizes. Either this makes the smaller frame sizes too heavy or the larger frame sizes insufficiently strong and stiff. Principia’s DESIGN 2 SIZE technology optimizes the tubing specifications for the individual frame sizes ensuring optimum riding characteristics for riders of all sizes.

Principia’s proprietary carbon technology combines first class carbon filaments with a newly developed layup technique. WPC technology allows maximum control of the direction of the fibres enabling us to carefully finetune key properties such as stiffness, strength and comfort. WEAVED PRINCIPIA CARBON exclusively uses Mitsubishi filaments with tensile strenghts ranging from 12 (C12T) to 40 (C40T) tonnes per square centimetre.

Principia’s INTERNAL CABLE ROUTING allows the gear cables to disappear discretely into the head tube giving the frame a unique, streamlined appearance while ensuring that the cables are protected from dirt and grime at the same time. Principia ICR has a completely sealed liner from entry to exit for easy maintenance and wire replacement.
