A few years ago, I tore up the seat that shipped with my Trek 4500 mountain bike (I foolishly tried extreme mountain biking!). I considered the Trek stock seat to be fairly comfortable. I replaced the torn stock seat with this one. I have HATED it since!This seat LOOKS great, but FEELS AWFUL! Even just a 30 minute ride causes my rear end to hurt into the next day. It is a narrow saddle with very stiff pads. Although I do much of my riding standing up, it still causes my rear end to hurt a lot. I feel my butt bones digging through onto the narrow saddle. I am a bit heavy (215 lbs) and probably require a wider seat. Beware - this seat is very uncomfortable!
