FIT MEETS FAST Every Sirrus® offers the speed and agility of a road racing bike,
paired with enhanced ergonomics and the control of a flat handlebar. A simple, light and worry-free choice for anything from
fitness-based training to commuting and event rides.
Inside Tech
The front end of our Sirrus models has "user-friendly"
written all over it: flat handlebars give you more control and easy maneuverability, wide-range gearing ensures confidence in varied
terrain, BG Comfort grips reduce hand numbness and a proprietary FACT carbon fork with vibration-damping Zertz™ inserts smoothes out your ride.
