I know its hard to recommend a seat because we all know everyone is different. Through my years I have had quite the intimate experience with many a seat some leaving tears in my eyes ( for a few days later). About about 4 years ago I found the perfect seat and after a few weeks I knew we were meant to be together forever!!
The WTB Laser V. (or the Pure V which is a tad wider with more cushion)
I immediately replaced every seat on every bike with it. If I sell a bike I take it off, and as soon as the wear I replace them...
I was just reminded about how important a good seat is yesterday when a casual solo ride at Wissahickon turned into a 4 hr tour of the place from some locals...
