It seems dnagerous for guy parts to me..but I dunno, maybe if you are wearing cycling shorts it wouldn't matter. It does also seem that your inner thighs would rub against it. For a girl, it may be better. I can see using that on a hybrid, like my montreal express, but I would never use it on a road bike! Even though I am currently riding with a men's saddle, a saddle is what I need, 'cause I don't just cruise through neighborhoods on my road bike, thats what the cruiser is for.
Thats like putting a western saddle on your steed for some crazy english fence-jumping..you just don't do it.
