Dialing in handlebar height on a Pinarello with an aero front end means working within the system's proprietary spacer stack. Standard round spacers won't work—the aero head tube profile and integrated stem design require spacers that match the airfoil shape and include an alignment pin for proper orientation. The Pinarello Headset Spacer Aero kit provides the frame-specific components you need: 2 spacers at 5mm and 2 at 10mm, giving you 30mm of total adjustment range to work with.

Each spacer is machined from 1K weave carbon fiber with parallel faces that sit flush against each other and the bearing retainer cap. The alignment pin built into each spacer indexes with the corresponding notch in the piece below it, ensuring the aero profile stays continuous from the head tube through the stem. Misaligned spacers create a visual break in the cockpit's lines and can interfere with cables routed through the TiCR internal system on equipped frames.

The 4-piece kit lets you fine-tune your stack in 5mm increments. Start with the combination that matches your current setup, ride it, and adjust based on how your fit feels over distance. Most riders end up somewhere between 10mm and 20mm of total spacer height once they've settled into their position. The matte carbon finish matches the aesthetic of the Talon and Tiger integrated cockpits these spacers are designed to complement.... Read More
