Specialized Tarmac SL8 Headset Spacer Kit SL7 Stem Aero OEM

Specialized Headset Transition Cover, Spacer & Stem Cover Kit – Tarmac SL8 w/ SL7 Stem

This genuine Specialized factory headset transition and spacer kit allows the Tarmac SL8 frame to be correctly paired with a Tarmac SL7 stem while using Tarmac SL8 aero spacers. Designed for clean integration, proper cable clearance, and factory-correct stack height, this kit ensures a professional, OEM-level cockpit fit.

⚠️ Important Compatibility Note:
This kit is not compatible with Tarmac SL7 stems shorter than 90mm. When used with shorter stems, the SL8 aero spacers will interfere with the cable bat on SL7 stems.

Ideal for frame builds, cockpit swaps, warranty replacements, or restoring proper fitment on SL8 bikes using SL7 stems.
