Specialized Sirrus

The Specialized Sirrus is a flat-bar road bike that provides a compromise between the low weight of Specialized's high end road bikes with more comfortable geometry. The bicycle pictured is the base version of the Sirrus model.

It comes with an aluminum fork, integrated headset and a 3D forged 2 bolt stem. Forged 6061 aluminum V-brakes allow for good mud clearance and wheels are made with Alex S500 aluminum rims that have CNC machined sidewalls for consistent braking. A Shimano Altus rear derailleur and an 8 speed cassette (11-32t) provide good performance at a reasonable cost and Body Geometry Comfort Grips on the handlebar provide a comfortable grip for long rides. The front triple chainring is a 48x38x28t, which means the bike has 24 gears and will be able to handle steep hills and fast descents. Tires are Specialized All Condition Sport 700 x32c, with a wire bead and 60 TPI (threads per inch) with Flak Jacket Protection for good resistance to puncture.
