I'm sold on the extreme forward position. A guy in our time trials group has what he calls a "nuts off the front" sitting style and he wears out his seat on the nose and his shorts in the same spot.
I've recently been trying out this sitting position and I have three comments:
1. It's uncomfortable and I worry about doing trauma to my perineum
2. It's noticeably more aerodynamic and faster, much moreso than an aero helmet plus 82 mm front wheel
3. It's more powerful with an increase in the area of 15-20 watts
So I really, really want to take care of #1 in order to get #2 and #3. Is there a triathlete seat nose that does your perineum right?
