Specialized Sirrus X 3.0 Step-Through EQ bike

The Sirrus X is your pass to long rides, to places you never imagined you could reach.

It’s a comfortable and capable bike, with a “we can do this” attitude, that will inspire you to pedal more and more. The semi-upright position, wide-section tires, intuitive 1x drivetrain, and compatibility with racks and fenders make the Sirrus X a reliable partner on asphalt, and thanks to the Future Shock system, suitable for some adventures on gravel roads too. Contact points like the saddle, grips, and pedals are built according to the Body Geometry Shared Platform standards.
