Specialized Sirrus X 4.0
Sirrus X 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 -it’s more than just a solid partner on pavement. Sirrus X is a dialled option when it’s time to hit some gravel. We’ve also equipped every Sirrus X with next-level comfort from our scientifically tested and ergonomically engineered Shared Platform Body Geometry saddle, handgrips, and pedals. We equipped 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.
