Setback seatpost ? How much is too much ?
Hi All,
I currently have a Thomson Elite straight seatpost. I have my seat pushed back as far as it will go. I am getting more & more comfortable sliding back in my seat and hammering climbs seated or even just hammering the flats this way too. I am wondering if a position even further back might be better. I would have to get a setback seatpost to accomplish this. The interwebs are full of articles about KOPS positioning not being too far forward but I haven't seen anything on what happens as you continue to move your seat further back. I know I would have to drop my saddle height as I move back to keep the same saddle height.
I am running a CAAD9, 56cm. I am 5' 10" @ 180lbs with normal proportions.

I went through the same process, gradually moving my seat back and getting comfortable with a longer reach. I got a Thomson setback post and I've been happy.

Yeah, I think I'm headed in that direction....I am reading some posts here on setback that I searched. So far the only downside I'm hearing about moving your seat further back is that eventually your back will get sore. So when you get to that point just move the seat forward until the soreness stops ?

You want to move back far enough so that you achieve the proper hip angle and a proper weight distribution on the bike. This obviously varies from person to person, but there are a few basic ways to check for this. The link below discusses a simple way to check the fore-aft position:

Personally, I am 6'0" tall with a 33.5" inseam and have found through trial and error (and backed up by at least one professional fitting) that I need at least a 25 mm setback seatpost for my frame which has a 73.5 degree seat tube angle (same as your Cannondale). The Thomson setback seatposts have 16 mm setback if I remember correctly. Also keep in mind different saddles offer different seating positions (extreme examples being ISM and SMP saddles).
