X5 105 Di2 Ultrafast 45 Carbon Wheel Road Bike

What Our Gearhead® Experts Are Saying:

"The X5 105 Di2 gives you comfort without turning mushy. The T700 carbon frame feels lively, the X Stays damp road buzz, and the Fulcrum wheels keep it rolling fast. Shimano 105 Di2 is simply dependable, and with 35mm clearance, this bike is ready for endurance miles on mixed pavement."

The Pinarello X5 105 Di2 is engineered around endurance comfort and long-distance versatility, using T700 UD carbon to balance responsiveness with vibration reduction. Endurance+ geometry provides a taller stack and shorter reach to create a more upright and adaptable fit. X Stays in the rear triangle introduce targeted compliance to absorb road chatter while maintaining stiffness at the bottom bracket for efficient power transfer. The asymmetric frame design compensates for drivetrain-induced forces, preserving balanced handling.

Shimano’s 105 Di2 12-speed groupset delivers electronic shifting performance matched with dual 160mm hydraulic disc rotors for predictable braking. The bike rolls on MOSt Ultrafast 45 wheels paired with Pirelli P7 Sport 35c tires, offering increased aero efficiency, lateral stiffness, and smooth rolling performance. With TiCR internal routing and 35mm tire clearance, the X5 is optimized for endurance riders seeking comfort, stability, and broad terrain adaptability.
