from Southborough, MA United States
I put one on my (Japanese) Paramount. There's a practical limit to what one can review about a headset, but here goes:
It's really pretty It's really nicely made The roller bottom/ball top thing doesn't come off as weird in any way It works just fine, in that the steering still feels fine -- a little stiffer than it was, but no pitting in the races It hasn't required any adjusting It still requires installation skills, grease, etc... unlike cartridge bearing headsets -- a good thing, I think
Despite this being pretty expensive relative to other perfectly reasonable headset options, it's nice enough that I'm going to buy another when they are back in stock (just tried to, now, but can't).
