Product Details
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 hourglass speedstays on the Specialized A1 Premium Aluminum Sirrus frame provide a smooth ride.
The aluminum fork has integrated rack and fender mounts, so you can easily add what you need to carry all your gear, comfortably.
Body Geometry Comfort grips prevent hand pain and tingling fingers.
With Shimano’s Revo 8-speed twist shifter, you don’t need to lift a finger to change gears.
The easy-on-your-soft-parts Body Geometry Fitness saddle is designed for long-term comfort.
