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
