I hope these changes help! Keep us posted.

My saddle is all the way back on the rails AND I have a seatpost with a fair amount of setback, too. If you have long femurs and a zero setback seatpost, I wonder if you're still not back far enough. I, personally, like to be farther behind my bottom bracket than the standard knee-over-pedal-spindle rule of thumb would suggest. Personal preference I guess, but it makes my knees and hands happy.
