The Sirrus X is your ticket to ride more and go places you never thought possible. It's a comfortable and potent bike that will inspire you to ride more than ever before. With larger-volume tires that provide more safety, a slightly more upright seating position, a super intuitive single drive and plenty of mounts for luggage racks and mudguards, it is more than just a solid partner on the asphalt.
- Lightweight A1 aluminum frame with clean internal cable routing, lighter than other bikes in this class.
- Maximum control with intuitive 1x8 gear shifting and powerful hydraulic disc brakes.
- Glide over rough terrain with the fast-rolling Specialized Pathfinder 42c tires with Gripton rubber compound.
