Do 31.8 bars fit in those 25.4 clamps? Just had a fiddle around and went on two quick 1 min rides and it seems like my bars are way too low. If I raise my stem converter as high as it'll possibly go it feels almost right, well exceeding min insertion. I think I need to size up... Here's some photos of what I've got set up at the moment.

No, you need a 25.4 bar for those stems. Nitto / Rene Herse and others make 25.4 clamp rando drop bars. Otherwise vintage riser or flat mountain bike bars will work. The only 31.8 clamp quill stems I've seen are for 1 inch head tubes.

If you really want to run 31.8 bars and threadless stems/headsets another option is to look for a used threadless 1 1/8th fork. Kona did make P2's in that configuration for a period and Tange, Surly, etc. made them for a while as well.

I'm sure you can find a bunch of similar forks on your local Amazon or Aliexpress. You can also probably find something used on your local facebook marketplace, Craigslist, etc. Just be careful the axel to crown and rake are close to what you're running now and you will be ok. Or keep using the threadless adapter.

You can get a high rise threadless stem as alternative as well. Here is an example from Decathlon

Wow thank you, this is super useful. I think I'm going to try find a bigger frame anyways. My commuter is an 18"!

Oh, I'd definitely want a touring bike to fit more like a commuter. Probably a good call. If you do replace it maybe look for something a little later vintage that has a taller stack height as well - those earlier bikes tended to be low and long for XC racing. Something in the 97-99 vintage perhaps?
