Several weeks ago, you kind people helped me to get a fork off a bike, and now I have some questions about getting it back in.
In the picture is the fork in question. When I removed it, it came out like this with the bearing ring sitting in this position on the steerer tube.
My questions are:
-
Is that headset bearing meant to be there or could/should it (ideally) have stayed in the head tube (like the other one did)?
-
Do I remove it and try to install it in the head tube again, if so?
-
If it’s not meant to be on the steerer but in the head tube, is it damaged? It spins freely as it should, but I don’t know enough to tell if there are other issues I should be seeing that would tell me it needs replacing.
-
Related but unrelated question – is it likely there’s an o-ring that should be installed somewhere in the setup of the fork and handlebars on the frame? I documented removal of all bits and their original location during disassembly, or so I thought, and have an o-ring that’s about the right diameter that’s unaccounted for.
Guidance and/or information is welcome and appreciated. Thanks in advance!
Info if relevant: Bike is 2012 Pinarello FP Quattro that I disassembled for a frame respray.
