I have been using a Selle San Marco short fix 2.0 carbon for a few years which has worked well. I had a small accident where i scuffed the saddle so decided to try the 3D version (Shortfit 2.0 3D carbon fx). After some use I find it to me much more uncomfortable on my sit bones. I expected the 3D would be more comfortable but it is not.
Any thoughts on why, given it’s the same saddle type etc
