oh wow
well, first thing english is not my first language so If I expressed myself wrong I apologize
true, photos are not the best, I was hoping that with the info I provided maybe was enough
I dont have a caliper at hand, I might order one...
I wasnt thinking to get one bc I thought this was a super simply thing that I can maybe help help in any LBS, but for some reason I went to so many around Harrow (UK) and I just had back luck
Also, I am a woman, just for some replies addressing differently
There is no number in any pieces, it was a sealed ring that literally explode when I was removing the stem
looks like I might need to
order a tool to remove the cups and a caliper to measure what I found from there and order a full headset after I know that, right?
I appreciate the patience, I am learning, I a just a young noob person trying to finish the bike
