Sirrus X is your ticket to riding more, and to places you never imagined possible. Its a comfortable, capable, lets 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 its more than just a solid partner on pavement. Sirrus X is a dialed option when its time to hit some gravel.
