Yeah, about just a few days ago I leveled my seat, and now with the handle bars a wee-bit higher than the seat, I'm not leaning forward on my pereneum. It's also definitely not aero, but that doesn't matter to me. I'm on a MTB with knobbies anyhow!
I've read some contrary info on crotch damage. Some places have said there's no such thing as permanent or serious damage. Other sites say there is. Better to err on the side of safety?
If I ever got numb down there you know I'd be off that saddle in a second!
