Would someone please explain the purpose of the Thompson setback seatpost. I did a little searching on Google and see what they look like but I don't understand why you'd want/need one of these over the standard (straight?) seatpost. It seems to me that you'd only need one of these if you can't achieve the proper kneed to pedal positioning - is that correct?

fubar5: Other than weight what benefits have you gotten out of your carbon seatpost?
