If you are positioned correctly, ( meaning correct frame size, position set-up etc.), you will never need to be concerned about this. Great cycling champions, Merckx,Hinault,LeMond and Armstrong to name a few ........... have children ! When they started manufacturing saddles with holes in the middle, some 8-10 years ago........, I had a good laugh ! I thought what a great marketing scam ! ! Having raced professionally ( yes, with LeMond,Hampsten and Phinney to name a few) from the mid seventies through the late 80's ....logging about 35,000 miles per season...... you would think I would be impotent if saddles[U
] really [/U] needed a hole in them. This was just good marketing to appease the people who did not have a clue about bike morphology. Like so many things in our culture......... throw money at something and it will fix the problem, ......... without taking a good look at what is truly causing the problem.
