I am hazarding a guess that it is not a quill.

Even though they have been rounded off, they still won’t have been torqued up that much or the thread would have stripped.
Is this the bike recently in the sales forum? Well bought, if so.

« Last post by andyoxon on Yesterday at 03:05:02 pm »Thx. I tried the torx bit earlier, size below too small, next one too large & didnt seem like it would hammer in - though I could try resting the side of the stem on a large vice & then try. I have steel drill bits so could try that method.
