This bike started out all Super Record, but has evolved over the years. My old legs no longer appreciated the 53/42 chainrings on the Super Record crank, so a Zeus 2000 with 48/36 chainrings has replaced it (factory drillium and Ti bottom bracket, of course). The Superleggero pedals were replaced by Look-made Campagnolo clipless pedals. The Record shifters were replaced by Simplex Retrofriction.
