yo where do i get this specific lower headset bearing? what keywords to look for? 51.8mm outer diameter, 8mm height, 45/45 degrees. note the large chamfer and it's solid metal on top instead of having the rubber seal on top. it can't be 45/36 degrees because my fork has an integrated crown race. i got cheap chinese 41.8mm and 52mm bearings and the 41.8mm worked, the 52mm seems to be compatible but makes a bigger gap between the fork crown and headset despite it being only 7mm in height because of the smaller chamfer.
