Exactly. I don't think that you're gonna find 'stache bars that'll fit the shifter/levers that come with the Baxter. I've done the 22.2 mm (MTB standard) bar to 23.8 mm 'stache bar conversion; you need to get new levers and a shifter. Since the Baxter has an Alfine, the only shifter options are the two that I mentioned earlier. If you were going from a larger diameter bar to a smaller diameter bar, you could shim the shifter/levers, but this isn't the case unfortunately.
