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 lives at the intersection of performance and value, which is why it’s spec'd with a bombproof assortment of components, like a crisp-shifting Shimano Sora rear derailleur, powerful Tektro hydraulic disc brakes with incredible stopping power, and comfortable Body Geometry touchpoints that’ll take the sting out of longer rides. Topping things off, you'll also find a step-through design that makes putting a foot down at a stop a total breeze. *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 Step-Through design makes this Sirrus extremely easy to get on and off, or to put a foot down. 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. And with a step-through design, getting on and off the bike
  • Scherpsturende Specialized FACT carbon voorvork, voorzien van Plug + Play bevestigingspunten voor spatborden.
  • Women's Body Geometry touchpoints take the sting out of riding with their ergonomically designed, scientifically tested shapes.
