Principia’s Internal Cable Routing (ICR) is sealed from the entry to the exit points for easy maintenance and wire replacement.   Stiffness, strength and comfort come together in the Weawed Principia Carbon (WPC) Technology. The carbon frames are made exclusively from high quality filaments with tensile strengths of 12, 16, 24, and 40 tonnes per square centimetre.
