Mega-9 is actually the moniker for ALL Shimano 9 speed drivetrains, you are thinking if Megarange with a rear mech that nearly touches the ground and a big sprocket like a dinner plate!
i'll have to look at the brakes again, but the shifters definitely have mega 9 drive on them. along with some kind of red line to indicate gear i guess. kind of like an automatic transmission. maybe i can get a pic.
