I bought a Giant Escape 2 about two weeks ago and have ridden it maybe 90 miles so far and wow does my rear end hurt. I plan to start commuting on this bike if weather permits as well. Is there going to be any big difference in switching from the Giant Connect saddle that the bike came with and something like the WTB Pure V Comp? I'm mostly riding casually/for exercise on mostly smooth roads/paved trails. I really just want a comfortable and inexpensive experience.
