I refurbished my bike and in the process got a new shiny quill stem to replace the original threadless stem. Unfortunately, like a dunce I forgot to ensure that the diameter of the stem adapter (the big bolt that connects the stem with the fork) fits the diameter of the fork. The quill stem adapter is ever so slightly larger in diameter than the fork.
I really want to keep both the brand new stem and the fork. Is there anything I can do to make them fit? Some sort of adapter to fit in between? Maybe a thinner bolt that fits the fork and the quill stem - and then somehow add "filling" between the new bolt and the stem? Open to any ideas.
It looks like I'm SOL. But in case this helps, here's the current threadless headset and the new quill stem I'd like to mount on somehow.
