I built mine from the ground up; using mostly high end Mountain componants for the deraileurs and crank and Ultegra shifting componants. With my FSA K-Force bar and Stiffster fork and a few other choice carbon goodies it'll look very sweet. And ride even sweeter. I will upgrade my front deraileur when SRAM brings theirs out. Until then it's an XT setup. I purchased a WTB seat but I am starting to second think that one.. Someday I'll get a nice Italian seat.
