Pinarello's integrated cockpit hardware is frame-specific, and the wedge that clamps the stem to the steerer is one of those small parts that doesn't cross-shop between generations. The Stem Compression Wedge Kit AM is the original replacement piece for the Most Talon Ultra Light handlebar stems used on Dogma F MY23 and MY24, as well as Dogma X — and it is not compatible with MY25 frames. If you've serviced an integrated cockpit on one of those bikes and need to replace a stripped, lost, or fatigued wedge, this is the part Pinarello specifies for the job.

The wedge sits inside the stem/steerer interface and converts bolt torque into the clamping force that locks the cockpit in position. On an aero setup with internally routed cables, that clamping interface is doing more than holding a stem to a round steerer — it has to keep the bar from rotating or settling under hard sprint efforts while working around the cable channels that run through the cockpit. A worn or mismatched wedge tends to show up as a creak, a bar that slowly noses down over a ride, or torque readings that won't stabilize at spec. Replacing the wedge with the factory part restores the intended clamping geometry and gets you back to a cockpit that holds its position.

MY25 Dogma F owners need a different part — Pinarello moved to the Flatback E-TICR wedge for that generation, and the AM kit will not interchange. Before ordering, confirm your frame year and that you're running the Most Talon Ultra Light bar. If you're on an older Most Tiger Aero or earlier Talon Aero setup, that's a separate wedge as well. Matching the wedge to the cockpit generation is the part of the job that prevents return shipping and a second service appointment.... Read More
