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 Sirrus Pro frame features our premium Az-1 carbon frame construction for the ultimate in stiffness and strength. Zertz inserts in the seatstays soak up vibrations for added comfort.
The S-Works Tricross carbon monocoque fork uses Speed Zertz to quell vibrations.
The 3D-forged Pro-Set alloy stem joins perfectly with the large-diameter handlebar for a solid connection.
The carbon-wrapped flat bar further absorbs vibrations and puts you in an upright position, adding comfort and control.
With a carbon-reinforced base and scientifically proven Body Geometry shape, the Toupé Gel saddle blends comfort with performance, the Zertz insert in the seatpost adds even more high-performance comfort.
