Conclusion: it works well
What you need is Paspots F1S full internal handlebars,
You need to machine the compression ring that comes with Paspots F1S
Since I bought mine a long time ago, I'm not sure if the ones released recently need machining or not (the stock compression ring has holes on the side, so full internal doesn't work)
In my case, the compression ring height was 2mm too high
so I went to a CNC machining shop and machined it 2mm
And when choosing a different handlebar, you should select one where the cable goes smoothly into the stem, not bent at 90 degrees
I had trial and error because there were no related articles, but please refer to this if you're doing full internal work
The shifting feel has no issues at all
