If we were to think of the two best improvements in the last decade when it comes to bike technology for urban cyclists it would be: hydraulic disc brakes and 1x drivetrains.
The Sirrus X 3.0 manages to get both alongside a nice aluminium frame, good quality tyres and comfortable contact points (saddle, pedal and grips)
Sirrus X is your ticket to riding more, and to places you never imagined possible. It’s a comfortable, capable, “let’s do stuff” kind of bike that will inspire you to ride more than you ever have before. With bigger, confidence inspiring tires, a slightly more upright riding position, a super intuitive one-by drivetrain, and plenty of mounts for racks and fenders —it’s more than just a solid partner on pavement. Sirrus X is a dialed option when it’s time to hit some gravel.
