I need to order some headset cartridge bearings. How do know which headset cartridge bearings are compatible with the bike and whether they will fit ?
I know the last ones I bought were these:

But there is no details on what size or spec they are or anything.
Whenever I have looked at the actual headset bearings, there is no details on them stating what size they are.
Measure the old ones. Then enter the dims into an online bearing shop bearing finder thingy. Eg simply bearings
Or look up the manufacturers spec sheets.
Measure; inner diameter, outer diameter, height, inside angle, outside angle.
there really should be markings somewhere on the bearings - usually on the shield. Might be quite faint
