Awesome, thanks for all the info! I always wondered why I could see so much saddle behind pro tour riders when they were really putting the hammer down.
I did inadvertently try riding “in the back seat” once time when I swapped saddles and didn’t get the bolts tight. The saddle had slid all the way back on the rails and I ended up with some ache in the back of one knee, I assume from my lack of hamstring flexibility.
At any rate, thanks for the great info. Lots to think about while I’m moving stuff around
