I got a good deal on a bullhorn bar to replace my flop and chop bar. I wanted to get a new stem too but I'm not a big fan of threaded/quill. I decided to try a quill to threadless adapter since replacing the headset and fork too would be too expensive. You can see the results below. In the second set, the adapter is pushed as far down as it would go but the skinny part still shows. I tried using headset spacers to cover it up in the third set. I'm just curious about what you guys think. I think it looks passable so I'll probably be keeping it for a while. I know it's not ideal but I always still have the option of either going full threadless or just getting a really nice quill stem.
