Most Rossin bikes, especially during the 10 Speed Driver era, were available as frame only and "kit" was available with some options on rim type, saddle, bar/stem etc. It was possible to buy a SLX custom painted frame and put RX100 on it or CroMor with C-Record.
Do these bikes have decals saying they are team bikes or replicas?
