The seatpost is a part of bicycles that gets lots of attention for style points. Some people like straight posts, others set back. Many carbon seatposts are on the market and some are incredibly light.
The function of the seatpost is to locate the saddle in the right place for your body. It is not rotating weight so its weight is not critical. Many people put form over function here and I get lots of questions regarding my recommendations for simple two bolt posts over the fancy lighter ones.
The simplest answer I give is, seatposts need to micro adjust for saddle angle. This is why I like posts like Thomson for two bolt models and Ritchey for single bolt models. My setup bike has many saddles mounted to seatposts and almost all of them are Thomsons.
Everyone’s pelvic floor is a little different regarding it’s angle relative to their spine. As such, everyone needs a little different saddle angle. This is much more pronounced on triathlon bikes. If your seatpost has little notches that have multiple degrees between each “setting”, odds are that your perfect match will be in between a detent.
Do you feel that your saddle is angled wrong? The seatpost could have something to do with it. Your saddle setback relative to the bottom bracket and the handlebar height and reach also play a big role. When I design a bicycle around you, this is another little point that is considered that impacts your comfort, efficiency and of course your satisfaction in choosing a KGS custom bicycle or frame.
