Description
The Sirrus X is your ticket to long rides, to places you never imagined possible. It's a comfortable and capable bike with a "we can do it" attitude that will inspire you to ride more and more. The semi-upright position, wide tires, a highly intuitive single-ring drivetrain, and the ability to mount a rack and fenders make the Sirrus X a reliable partner on the road and, why not, even for forays onto gravel roads. Contact points such as the saddle, grips, and pedals are designed according to the Body Geometry Shared Platform criteria.
