Sirrus Elite Alloy – Men's Spec

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. This Sirrus features an light and durable aluminum construction, as well as a reliable set of components that are built to withstand years of daily abuse, like 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.
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.
Body Geometry touchpoints take the sting out of riding with their ergonomically designed, scientifically tested shapes.
