I bought a used 2021 Giant Defy this spring. I ended up replacing the wheels. I’d like to use the Giant PR2 wheels as some (very) light gravel wheels, for some playing around. The rear bearings were shot, so I decided to replace them, and figured I’d replace the front bearings while I was at it. Rear bearing replacment was unduly complicated, but I got it done. They spin smoothly now. But I cannot get the front hub bearings to seat. I mean . . . not at all. I tried 2 different new bearings, and then tried to reinstall the old bearings. In every case, there is no movement at all even with tremendous pressure (and two different bearing presses). When I remove the press, the bearings just fall out. Yes, I greased the cup and a thin coat on the outside of the bearing(?). I’ve replaced headset, BB, and wheel press fit bearings without an issue before.
I am using 15267 bearings and 15267 bearing press insert.
