Specialized Sirrus X 5.0 Carbon Hybrid Bike
Specialized's Sirrus X 5.0 Carbon Hybrid Bike stands for lightweight comfort and speed across varied terrain. Rider-First Engineered™ technology, seen across the Specialized range, means the layup and geometry of each size of frame is uniquely crafted for balanced rigidity, weight, and responsiveness; no rider has to compromise. The FACT 9r carbon frame includes a Compliance Junction for flex and forgiveness with no drop in efficiency. Future Shock 1.5 is another comfort feature, in which suspension is placed inside the headtube to prevent harsh bumps from reaching the handlebar.
SRAM's NX Eagle 1x12-speed drivetrain keeps things simple and efficient, providing a wide range of gears and smooth, reliable shifting, while Tektro hydraulic disc brakes deliver powerful all-condition stopping power. Strong alloy wheels are fitted with Specialized Pathfinder Pros in a 38mm width, a tubeless-ready tyre that is capable on a range of terrain, enhancing traction and comfort.
Mounts on the top tube and fork allow attachment of mudguards and rack, maximising versatility so you can get to your destination dry, clean and with everything you may need for the day ahead.
