Integrated Shifting Precision

BACKGROUND

It was our goal to develop a rear dropout that combined the precision and stiffness of an integrated design with replaceability in case of an accident. Principia’s unique and patented rear derailleur hanger is one of the most advanced on the market.

TECHNOLOGY

  • 7005-aluminium for extra long life.
  • Ultra low weight: 15-grams.
  • Large contact surface with the frame improves gear change performance.
  • Optimum stiffness from four, multidirectional fixing bolts.
  • Available in five different colours to match individual preferences.

HANDLING

  • Most cyclists agree that a precise gear change is vital for the ride experience. What fewer cyclists realise is that the precision of the gear change is determined by the design and stiffness of the rear derailleur hanger. On your Principia, you will experience the gear changing performance of a fixed rear dropout from our replaceable design.
  • You can ride more freely and be more aggressive with your gear changes when you know that a small mishap will not mean the end of your frame.
