I have a '94 XO-3 which I bought new back then and a Sam Hillborne
which I bought this year and equipped with new Riv moustache bars.
Both bars measure the same. Both fit a 26.0 stem - I've played
musical handlebars on both bikes with other bars. I find both to be
as comfy as all getout. I had no trouble doing a 50-miler on the XO-3
recently even though the frame size is way too small for me. I added
Velo Orange Dia Compe Knob Grips to the Sam bars halfway between the
brake levers and the stem, however I don't have enough miles on them
to have an opinion yet. Once I crank out some long miles with them
I'll know.
