The RS-1 bike came with a Campy Tandem rear hub to accommodate the disc brake rotor. Fisher bought 1000 of them at an outrageous price to fit onto the RS-1. I remember disassembling one to repack it and spilling a lot of tiny ball bearings all over the floor-was a nightmare to find them all and get it back together again!
