Pinarello

X5 105 Di2 Ultrafast 45 Carbon Wheel Road Bike

What Our Gearhead® Experts Are Saying:

"I’ve been really impressed with how the X5 handles long, rough miles. The T700 carbon frame and the X Stays do an incredible job muting vibration without making the bike feel sluggish. Shimano’s 105 Di2 gives it modern precision, and the added tire clearance opens up routes I usually reserve for endurance bikes. If you want a bike that’s comfortable without giving up responsiveness, this one hits the mark."

We reach for the Pinarello X5 105 Di2 when comfort, stability, and long-distance enjoyment matter just as much as speed. Built with T700 carbon and shaped around Pinarello’s Endurance+ geometry, the X5 encourages a relaxed and confident position on all-day rides. The higher stack and compact reach help us settle in for miles without sacrificing the agile road feel we expect from a performance-focused bike.

Pinarello’s X Stays bring impressive vibration absorption through the rear triangle, softening rough pavement while keeping the bottom bracket area reactive under power. The Shimano 105 Di2 drivetrain shifts smoothly across varied terrain, and the generous clearance for 35mm tires gives us the freedom to explore paved roads, broken backroads, and everything in between. Paired with MOSt Ultrafast 45 wheels, the X5 gains aerodynamic speed and a stiffer, more responsive ride feel while maintaining the endurance-focused comfort of the frame.

Heads up - We do our best to keep bike specs and images current, but occasional component changes can happen without warning-and sometimes the photos might not show the exact build you'll receive. If you want to double-check the details, our Gearheads are always here to help.
