Product Details
We understand that fitness bikes can get a bad rap. Most of the time, they err on the side of value over performance, which leaves YOU feeling in between, and frankly, a little burned. But we're happy to say that our Sirrus is out to change that by providing the perfect blend of everyday efficiency with the performance you need to hit your fitness goals at speed. As the starter bike to the Sirrus line, this model is spec'd with a mix of Shimano components that'll keep you pedaling worry-free for miles, powerful hydraulic disc brakes that provide reliable stopping power in any condition, and comforting Body Geometry touchpoints that are sure to take the sting out of long rides. *While this frame platform was designed from the ground up for all riders, some of the models feature gender-specific touchpoints.
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.
A straight blade steel fork provides a responsive ride, while the fender and rack mounts give you the option to install fenders and racks that can keep you dry and transport your gear around town.
Body Geometry touchpoints take the sting out of riding with their ergonomically designed, scientifically tested shapes.
