Off-set Seat Post

If my saddle is currently adjusted to the most rearward position with a non-offset seatpost (Cannondale C3 27.2x300), should I consider running an offset seatpost?

You'll be surprised to find out that there is a fair amount of disagreement over bike fitting issues like this:

I'd do some reading but the basic idea is that if this position is working for you, I wouldn't change it unless you have a good reason. Personally I prefer a seatpost with some setback because I find that this enhances stability and rideability but that's my bike and my body. YMMV.

Thanks, I guess I will ask my LBS for their input as well. They have a good reputation for bike fitting, so they have some insight to my particular setup. I'm making a stop by there to pick up a new saddle anyways.

If you need to move it farther back, a set-back seat post is one way to do that. KOPS with all its controversy is just one way of thinking about that.

I tend to agree that unless there's some reason to change it, you certainly don't need to.

If the seat is where you want it, if you don't have problems with the post head flaring the saddle shell, if rail flex isn't an issue, and you don't mind the looks, then what is to be achieved by switching posts?

If you've been wanting to swap your post out anyway for whatever reason, then I'd say yes, go with a setback post because, first and foremost, it'll look better! Balance, feng shui, and all that.

There are seat posts with a variety of different set-back ,
your LBS can at least see what Diameter you have , and need on your bike..


I swapped out , eventually, a zero set back suspension seat post ,
for a cane creek, Thudbuster, that has setback.


there are saddle rail differences as well , some allow more adjustment range, than others..

the Zero -setback post + a B17 saddle was a No-go for me,
unless the frame was replaced for one having a lower seat tube angle.

After consulting with some local fitters and friends who know a lot more than me, I was told that sometimes having the saddle so far back can transmit force that should be more evenly distributed (i.e. the post should be closer to the middle of the rails, and not out at the extreme like mine), and lead to discomfort. So, in my search for the perfect saddle I've decided to go ahead and install a new setback post to reach a more 'ideal' position. I placed an order for a Deda Superzero. On the plus, carbon is cool, and I save a few grams so now I'll be even more super fast and sexy
