Not sure what Shadow you ride exactly, but here's the setup on my Shadow Spirit 750:
Custom World International Highway Pegs. They didn't quite give me the stretch that I wanted so I ordered up some Scootmods forward controls on the cheap. If everything works out right I'll be able to keep the Highway Pegs with the new setup.
Just got the stuff from Scootmods, haven't had a chance to mount them yet cause of the snow, but they look like solid parts.
