X5 105 Di2 Fast 45 Carbon Wheel Road Bike

The new Pinarello X5 road bike isn't a stripped-down X7. It runs its own T700 UD carbon layup, calibrated for compliance rather than the stiffer T900 found on the X7 and X9, and pairs it with a separate bar and stem setup that makes fit adjustments and component swaps more straightforward than the integrated cockpit used elsewhere in the range. Shimano 105 Di2 handles shifting, and the new adaptive seatpost adds real flex at the saddle, a detail that carries extra weight on a bike built around long days in the saddle.

What Our Gearhead® Experts Are Saying:

"I've pushed 105 Di2 through hard intervals and the shifts stay crisp under full power, no hesitation on a hard effort. Standing to sprint out of a corner, the T700 frame still transfers power cleanly, so the extra compliance never shows up as flex where it isn't wanted."

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 Gearhead® Experts are always here to help.
