This headset top cover was designed as a titanium alternative for the stock Specialized Crux top cover, but it's compatible with all standard 1-1/8" headsets. Stack height is 6.5mm. 

Fits bearings with an OD of 41.80mm or less.

ID fits standard 1-1/8” steerer tubes.

Remember, Specialized Crux customers should transfer over that rubber insert if they are upgrading their plastic spacer to our Ti spacer.

Lightweight 13g. Made in San Diego.
