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 are riders—that fact has guided our every decision since 1974. When quality tires weren't around, we strove to make the best. When people wanted to ride cruisers in the dirt, we made the first production mountain bike. When roadies wanted to go faster, we doubled-down on carbon and built our own wind tunnel. And when we saw kids struggling to focus in school, we started the Specialized Foundation to help them through cycling. Specialized. Made for riders, by riders.
