X9 Disc - Dura Ace Di2 - Most Ultrafast

The carbon layup on this frame is a game changer on rough chip-seal roads—I felt dramatically less fatigue after a 60-mile ride than on my previous aluminum setup. The Di2 shifting is crisp and the geometry keeps me comfortable in the drops for hours.

The vibration absorption from that carbon layup is unreal—I rode 60 miles on rough chip seal and my hands and back felt fresh at the end. The frame just soaks up the buzz without feeling dead or sluggish. Exactly what I was hoping for.
