Simplex didn't completely copy Campy's design. When you crash hard on a Nuovo Record derailleur, you have a bent up unit that shifts worse than normal. When you crash on a Super LJ derailleur, you have a broken unit that won't even get you home.
Steve Barner, want to see my drawer of broken SLJs and Suntour Vs in Bolton, Vermont?
