I will try to remember to look at my bars tomorrow. My shoulder width measurement was 38 and I *think* that's my bar size, too. I know whatever I have is about as narrow as one can find in stock bars.

Related--mine are flat across...kind of elliptical-shaped, rather than perfectly cylindrical, then they have standard drops. LOVE them. I can't imagine perfectly round bars. The flat ones really spread the pressure out nicely.
