Notchy steering feel when centering the bars, grinding sensation during slow-speed maneuvers, or play that won't adjust out with headset preload—these symptoms point to worn headset bearings. The Pinarello Dogma Headset Bearing Set provides the OEM replacement components for Dogma 65.1, F8, F10, Prince, GAN, Grevil, and Crossista frames, matching the specific angular contact geometry these head tubes require.

This is a complete 4-piece set: upper bearing, lower bearing, crown race, and split ring retainer. The Onda fork on these frames uses a 1-1/2" to 1-1/8" tapered steerer, which means the upper and lower bearings have different diameters and angular surfaces that must match the frame's bearing seats precisely. Generic bearings with the wrong contact angle or race dimensions won't seat correctly and will wear prematurely or cause handling issues. Pinarello machines these components to the exact specifications the frames were designed around.

The angular cartridge bearings use stainless steel for both the races and ball bearings. Stainless resists the corrosion that develops when sweat runs down the steerer tube or when you're riding through wet conditions regularly. The sealed cartridge design keeps contamination out of the bearing surfaces, extending service life compared to loose-ball alternatives.... Read More
