Denmark’s Principia just sent over these images of their new Revolution road bike, the first complete bike we’ve seen with thru axles front and rear, built with Dura-Ace Di2 and the just-announced Shimano hydraulic disc brakes.
Principia has been around since 1990, primarily sold in Europe with no current US distribution. The Revolution is a completely new frame for them, and Principia’s Andreas Hagbarth says the layup was designed to “achieve ultimate stiffness with the new axle system” while still offering an all-day comfortable ride.
Besides the new frame, it’s sporting plenty of the newest parts like the new FSA K-Force Light BB386 asymmetric crankset, which drives rolls on custom DT Swiss Revolution wheels designed around the 15mm front and 142×12 rear thru axles.
Up front is a tapered headset holding a custom fork designed for 160mm rotors and post-mount brakes with the DT Swiss 15mm thru axle.
The frame is Di2 ready. Hagbarth says it’ll work with either SRAM or Shimano disc brakes…we’re just not sure what you’d do with a SRAM mechanical drivetrain here.
The wheels were co-developed with DT Swiss using a 38mm disc brake only 700c full carbon rim. They’re laced with Aerolite spokes, and the hubs are based on 240s Classic with some customization to fit the frame and are 11-speed ready.
