25.4mm is the mountain bike standard, so you can use any "mountain
bike" threadless stem made since the beginning of time.

If you want to use a "road" stem, you'll need to use the shim to fit
those bars in the road-standard 26.0mm clamp.

Use any threadless mountain stem, like some from Ritchey. 25.4mm clamp.
