Verified OwnerNot sure what bike this is supposed to fit, but the spacing required from the top of the bearing to the top of the head tube is unlike any other I've seen, and where the "Slam" gets all of it's gains from - rather than from the design of the slam itself. So odd. All seals have been removed from the design. Recommend searching a competitor product if you're looking for a normally sealed 'slammed' headset for a standard headtube configuration.
