I bought a used T1 and want to put bullhorns on it. I could use a shim and put my Soma or Nitto bars on, but since it already has the 31.8 stem, I'd like to try try some 31.8 bars to get the extra stiffness people say the larger diameter gives. (And with the stock road road bars, it does feel very solid.) Any recommendations? I read a couple old threads but wanted to hear what's new. Most of the bullhorn/TT bars I've found are 25.4 or 26; nitto, soma, easton, profile design.
