Looking for a new way to break a sweat? Need a reliable, lightweight bike to get you around town? Want a bike to simply cruise to a coffee shop on? No matter what your goals are, the Men's Sirrus SL has you covered.
It's constructed from a durable, reliable, and lightweight A1 SL Premium Aluminum, and it features a bombproof assortment of components, like a Shimano Acera rear derailleur and powerful Promax hydraulic disc brakes that are sure to get the job done. This model also has a step-through design that makes putting a foot down, or getting on or off the bike, a total breeze.
Sprinkle in some added comfort from our proven Body Geometry components, like the grips and saddle, 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.
- Working with our Body Geometry team, we designed a frame that strikes the optimal balance between comfort and efficiency. The A1 SL Premium Aluminum construction pairs weight savings with rugged durability, while the rack, fender, and disc mounts give you an incredibly versatile package.
- The lightweight FACT carbon fiber fork provides a smooth, responsive ride, while the Plug + Play fender mounts give you the option to install rain-fighting fenders.
- Promax F1 hydraulic disc brakes are spec'd on this Sirrus to ensure consistent, powerful braking.
