This is a great saddle. Similar to the Specialized per power saddle with a slightly wider nose and wider relief channel. For me personally I find this slightly more comfortable, but everyone's bum is different.
Certainly wins in the looks department.
After having the specialized power saddle for one season I switch to the pro carbon. The nose is a little longer with more support and overally slightly wider. Bigger cutout. For the price in carbon its also alot cheaper
