I did the paper on the hard floor measure, as well as folding my yoga mat in half and measuring the indentations. 7 inches both times. Somehow, I'm not surprised. Runs in the family. The saddle width of the Velo Plush on my bike is about 6 inches at its widest, and I have been wondering about whether I could be more comfortable than I am as my rides have gotten longer. I think I'm going to take a hard look at the B-67.
