As you push yourself towards your fitness goals, you need a partner that you can count on, and we're happy to say that the Sirrus Sport EQ - Black Top Collection fits the bill. And with its Step-Through design, it makes getting on and off the bike, as well as putting a foot down, a total breeze. It's constructed from a durable, reliable, and lightweight A1 SL Premium Aluminum, and it features a bombproof assortment of components, like a Shimano Sora rear derailleur and powerful Tektro hydraulic disc brakes that are sure to get the job done. 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. To complement the above features, this Sirrus falls into our Black Top Collection. Designed to be discrete when viewed from afar, our Black Top bikes attract less attention, helping to ward off theft. They also have subtle hints of color on the underside of the fenders and saddle, as well as a reflective "Specialized" wordmark on the down tube—making for the perfect blend of style and peace of mind. Lastly, you'll find that this Sirrus comes fully equipped with fenders, lights, and a rear rack, so lugging your stuff around, no matter the time or weather, just got a whole lot easier. *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.
  • Braking duties are handled by Tektro hydraulic disc brakes to ensure effective, consistent, and reliable power through any kind of terrain or condition.
  • The front Shimano Dynamo hub houses an energy production system that will power your front light for as long as you want to cruise down the road.
