This definitely does not have the padding.I cant understand why they can't maje a carbon shell with lots of padding. Some of us like a hard shell with gel and more padding. I was really hoping this had what it takes to be different but they are all worried about weight.If u made a carbon shell but put 8-10 more grams into the padding for us long distance riders we would buy it. Just make a limited supply (like 50). I think u would be supprised at how fast thet would sell ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Great saddle. Have two now. *by A***R on Reviewed in the United States on July 1, 2017* Great saddle. Looks great and feels great. Have two.
