The seller had the original Rolls saddle, so I used that. I replaced the seatpost, stem, and bar with ones more suited to me, and got rid of the hideous chartreuse bar tape. Apart from that, it was just cleaning, polishing, repacking the headset, bottom bracket, and hubs, and new cables, housing, and tires. Oh, and one black rubber nub, for the front brake pivot bolt.
