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 tyres, 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 dialled option when it’s time to hit some gravel. Every Sirrus X comes with next-level comfort from our scientifically tested and ergonomically engineered unisex Body Geometry saddle, handgrips, and pedals.
The Sirrus X 4.0 is equipped with the revolutionary Future Shock to take the sting out of bumps and potholes. Here’s to your life on two wheels.
Future Shock 1.5 delivers 20mm of compliance to give maximum comfort and control over the rough terrain.
Added Carbon Fork and an A1 SL alloy frame delivers a build 800 grams lighter than the 3.0 model–no heavy hybrid featuring a mountain style suspension fork comes close.
Wide-range 1x11 SRAM NX shifting delivers precise shifting for the long haul.
