Dogma X Dura Ace Di2 PM Grit 4540 Carbon Wheel Road Bike

The new Dogma X routes road vibration through four contact points with X Stays 2.0, and a lower linkage keeps rebound in check over long miles in the saddle. A narrower, tapered downtube adds lateral stiffness, so climbs stay reactive without costing speed on the flats. Up front, an elliptical steering tube widens the head tube for extra torsional stiffness while narrowing the overall profile, sharpening handling into fast descents.

What Our Gearhead® Experts Are Saying:

"I don't think about upshifts when my hands are cooked three hours into a ride, because Di2 fires the same crisp shift whether I'm fresh or fried. The integrated power meter keeps me honest on climbs, so I pace off the number in front of me instead of how strong I feel in the moment."

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.
