Technical Specifications
IF YOU'RE ONLY GOING TO HAVE ONE BIKE the Sirrus is it. Built for the best balance of speed and control, every FACT carbon or A1 Premium Aluminum Sirrus combines the low weight, high comfort and easy speed of our performance road bikes with the enhanced ergonomics and stability of a flat handlebar.
  • The A1 aluminum frame features seamlessly integrated carbon seatstays, with vibration-absorbing Zertz inserts.
  • The lightweight and strong Sirrus carbon fork features a carbon crown and steerer.
  • The stiff and strong 3D-forged Comp-Set alloy stem joins perfectly with the large-diameter handlebar, giving you absolute control.
  • Body Geometry Comfort grips prevent hand pain and tingling fingers.
  • The scientifically proven Body Geometry Sonoma saddle reduces pressure on your soft parts, the carbon-wrapped seatpost helps absorb vibrations.
