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 dialed 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.
