The Specialized Sirrus X 2.0 Aluminum 8 Speed Disc Hybrid Bike is your ticket to riding more, and to places you never imagined possible. The Specialized Sirrus X 2.0 Aluminum 8 Speed Disc Hybrid Bike is 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 1x8 wide range gearing, and powerful hydraulic disc brakes.

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