The Sirrus X is the ultimate all-terrain companion, offering an unprecedented balance of comfort, efficiency, and agility. Whether you're navigating city streets, gravel paths, or dirt trails, this bike is engineered to excel on every surface in between.

Smooth, Comfortable, and Efficient

Designed to provide the smoothest ride in its class, the Sirrus X features high-volume, confidence-inspiring tires and a slightly more upright riding position. The super-intuitive one-by drivetrain simplifies shifting, allowing you to focus on the journey rather than the gears.

Rider-First Engineered

Following the same philosophy as our top-tier performance bikes, every Sirrus X frame geometry is uniquely crafted. Each tube size is specifically selected to achieve the perfect balance of rigidity, weight, and responsiveness. This ensures that every rider—regardless of frame size—experiences the world’s best ride quality.

Nimble and Lightweight

This model is even lighter and faster than the Sirrus X 2.0, thanks to the addition of a premium A1 alloy fork. Combining class-leading lightweight construction with exceptional pedaling efficiency, the bike offers "telepathic" handling and precise steering for total confidence on any road.

At a Glance

  • Upgraded Fork: Features a lightweight A1 alloy fork for increased speed and reduced weight compared to the 2.0 model.

  • Wide-Range Drivetrain: 1x9 Microshift Advent system with an 11-46t cassette provides excellent range for both steep climbs and fast flats.

  • Hydraulic Braking: Equipped with powerful hydraulic disc brakes for superior stopping power and long-term durability in tough conditions.

  • All-Terrain Tires: Bigger tires designed to inspire confidence on pavement, dirt, and gravel.
