This time, I added some clipless pedals and a new Serfas Dorado saddle and Kalloy Uno seat post (26.8mm) to replace the old Brooks leather saddle and steel seat post that had seen better days. A Shimano RD-M700 Deore XT rear derailleur handles the shifting in back, it'll shift up onto the big 34T sprocket and actually will actually handle 41 teeth of gear change.   (3/11)
