Specialized Sirrus X 2.0

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 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.

Lightweight A1 Alloy frame with clean internal cable routing, 3.5lbs (1.7kg) lighter than our Crosstrail Hydro model.

Maxiumum control through hyper intuitive shifting with 1×8 wide range gearing, and powerful hydraulic disc brakes.

Float over rough stuff with fast rolling Specialized Pathfinder 42c tires featuring proprietary Gripton rubber compound.
