SRAM D.I.R.T shifters are 9 speed shimano compatible. They are basically Sachs Shifters after SRAM bought them out. You can still get them NOS but not in RED I'm afraid. Look at the Porsch bike in my signature, as I am running them on it.
I continued searching all evening about older grip shift and probably I will move to 3x8 as I can get a nice set of NOS Sachs Power Grip Wavey Shifters. I don't care about the number of gears and gear parts are that cheap.
