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.
