Threadless stem conversion

And I do mean literally. I must be the only person mad enough to have converted a low-end quill stem to threadless like this. Seems to have worked out pretty good though. I'm thinking of welding the very 90s bar-ends onto the actual handlebar (also made of steel but painted to look like aluminium) a bit further in for a sort of soft-road gravel-cross/adventure semi-aero position.

Just realized my custom bar end idea isn't going to work unless I weld them on after attaching the bar to the stem and don't mind that it's never coming off again.

Which I don't really. Was originally going to make this stem with a bit of old steerer and just weld to the handlebar instead of making a clamp. But the original stem looked stiffer being ovalized.

Weld another pinch bolt on there and make the faceplate removable

That's the other option but it might need two pinch bolts. Just one at the top and one at the bottom might be too sketchy for when I'm sending it, laying waste to the trail etc. Stems that are like that usually have four bolts (although they're usually also aluminium).

​​​​​​There's really nothing wrong with having the handlebar and stem one-piece. The only reason they're not usually is just so you can swap parts around which I don't plan on doing.

Not decided yet whether to do inboard bar ends. It seems they might work quite well for ergonomics.

it seems to me that whenever I decide I'm not going to have to take something apart, that is quickly overcome by events. You could have the only stem faceplate with 3 bolts.
Or 5

We've seen a number of home done set ups with bar ends located inboard of the grips/levers. I have a good friend who's done the same with his Jones barred bike. Although i wouldn't weld the bar ends on as I would want some future adjustment ability. Andy

It turns out the bar ends actually fit inboard anyway, using the pinch bolt things they already have. So I'll probably try inboard, but no need for me to ruin everything by welding it all together at this point!
