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 than Sirrus X 2.0, and faster thanks to an added A1 alloy fork. Wide-range 1×11 Shimano Deore drivetrain with a 11-42t cassette gives excellent range on any road. More powerful hydraulic brakes and premium 2-piece crank design for enhanced braking power and durability in tough conditions. Racktime rack for your favorite bags and panniers, and integrated DRYTECH fenders to keep the spray away. Extra-bright front and rear lighting powered by a Shimano Dynamo hub to see and be seen.
