Titanium Headset Slam Cap

Our titanium Slam Cap was designed for Specialized Crux, but it's compatible with all standard 1-1/8" headsets. Adding just 0.75mm stack height to your front end, this is the closest you'll get to running it without a headset top cover at all. Fits bearings with an OD of 41.80mm or less. ID fits standard 1-1/8” steerer tubes. Featherlight 4g. Made in San Diego.
