I have 44's in the front and 42's in the back. The back is a Profile bullhorn that is slightly tapered inward towards the horn tips. My wife likes to ride more upright, so they are a little narrow for my hips when her hands are on the horns. I'm changing hers out for a Profile 44. If you want the 42's, I'll make it worth your while. They are less than a year old. Here is the Profile site
