Specialized Sirrus X 4.0 Disc Hybrid Bike

The Specialized Sirrus X 4.0 disc hybrid bike is your ticket to riding more, and to places you never imagined possible. It’s a comfortable, capable, “let’s do stuff” kind of bike that will inspire you to ride more than you ever have before. With bigger, confidence inspiring tires, a slightly more upright riding position, a super intuitive one-by drivetrain, and plenty of mounts for racks and fenders — the Specialized Sirrus X 4.0 is more than just a solid partner on pavement. Specialized Sirrus X 4.0 is a dialed option when it’s time to hit some gravel. Specialized also equipped every Sirrus X with next-level comfort from our scientifically tested and ergonomically engineered Shared Platform Body Geometry saddle, handgrips, and pedals. Specialized equipped the Sirrus X 4.0 with the revolutionary Future Shock to take the sting out of bumps and potholes. Here’s to your life on two wheels.
