I did this for the same reason. If the stem does not have a removable face
plate the bends in the road bar will not fit through the hole in the stem. Get
a one inch ******* (half round) file and enlarge the hole. The radius of the
file and the radius of the hole match closely so it is easy to enlarge the hole
evenly. Check you work by trying to put the bar into position in the stem. If
the stem head is aluminum you should be done in 15 minutes. Steel may take much
longer.
I was amazed that the 0.6mm difference in diameter is enough to prevent the
bends in the road bar from passing through the hole in the stem.
