Product Details

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.
An A1 Premium Aluminum 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.
Tektro hydraulic disc brakes are reliable and powerful, putting out dependable stopping power in almost any condition imaginable.
