Nice bars, traditional diameter

what do you mean oversized? as in 26mm, or the literally oversized one with a 31.8mm clamp diameter?

Literally oversized... the bars are Bontrager Bullhorn 31.8mm (just looked)

two - you can use a different stem.
Hmm. LBS said they couldn't find a stem that would fit inside the forks, that would accomodate oversized bars. Don't know how hard they looked, though.
