If your approach to fitness is no-nonsense and straightforward, our Sirrus Disc is for you. It's constructed from a durable, reliable, and light A1 Premium Aluminum, and it features a bombproof assortment of components, like mechanical disc brakes and Shimano shifting, that are sure to get the job done. Sprinkle in some added comfort from our Body Geometry components and a Fitness geometry that lives in the sweet spot between comfort and performance, and you have a bike that'll always be ready to go when it comes time to sweat.  
  • The reliable and sturdy A1 Premium Aluminum frame features rack and fender mounts, allowing you to carry gear or to fend off road spray in inclement weather.
  • A steel, straight blade fork provides a responsive ride, while the fender and rack mounts give you the option to install rain-fighting fenders and racks that can transport your gear around town.
  • Mechanical disc brakes are reliable and powerful, without the hassle of brake bleeds and labor-intensive maintenance.
