On mine the only thing stock was the frame, fork, crankset, headset and stem. I added the Trp 960's, Pro race 3 tires, Ritchey bars, tape, 105 shifters and derailleurs, Spinergy Spox, aluminum post, Ti Zero's, Gortex brake and shift cables and specialized seat. It rides incredible and rolls fast. The only thing I am going to change is the chain since its 105 and the cogset is a new dura-ace. For some reason the chain doesn't play nice on the cogset so I ordered a KMC X10Sl.
