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.
- Even lighter (1.6 lbs/.8kg) than Sirrus X 2.0, and faster thanks to an added A1 alloy fork.
- More powerful hydraulic brakes and premium two-piece crank design for enhanced braking power and durability in tough conditions.
- Wide-range 1x9 MicroSHIFT drivetrain with a 11-42t cassette gives excellent range on any road.
