i keep seeing a lot of peoples bikes with the nose of the seat pointed up. this is not a good thing the vibration and the pressures are not good for that part of your body. i used to race bicycles and mountain bikes and know of a lot of young people that went sterile from this. you want to take a level and put your seat as level as possible and then tip the nose down just a fraction. i have a good friend that is a doctor and has commented about the same thing. don't let this thread turn into comedy hour please. i know a lot of you are like me reading it thinking good comebacks. i know i sure would lol. but this really is serous
