Knotted, I am on a narrower side. I had Specialized jett in 144 mm and it was a good size for me except that saddle just HURTs. So 177 mm would be a little too wide for me. I am trying to save a little money right now for my vacation in may, so that's why I am attracted to Nashbar deal on B17 N. Although, if Selle anatomica is a better saddle for me I will definately buy it.
