Works great at a great price
I bought this to replace the headset bearings on my Ozark Trail G1 Gravel bike. The bearing that come with the bike are open race and terrible. So when I changed out the front fork to a carbon fork, I needed something better than what came with the bike. These were easy to install, just needed to hammer out the old cups and then used a dead blow hammer to press the new cups into my head tube. Now there is zero slop with my fork and it rotates super smooth.

Came quick. Worked perfectly.
Worked perfectly on my ztz fork that I installed on my jasion x hunter st. I did buy a headset press and needed it for installation.

Great replacement / upgrade !
Don’t let the price fool you! These bearings, cups, and races are all pretty good quality. Even if the bearing fail in 6 months I now have the cups needed to run the most standard size headset bearings!
