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 other bikes in this class.
- Maximum control through hyper-intuitive shifting with 1x8 wide-range gearing, and powerful hydraulic disc brakes.
- Float over rough stuff with fast-rolling Specialized Pathfinder 42mm tires featuring proprietary Gripton rubber compound.
