I went to my local bike shop with bike in hand and they suggested I stick with my 700c x 38 because of my build. I am not a typical road biker weighing 160lbs or so. I am 210lbs and look more like a football player. She said I might be able to get away with a 700x32 at the max, but she said I would probobly be happier overall with the 38's.
So I took her advice. They are made by bontrager.
