333, and 3CC. My two favorite hubs in the entire world. I have never found a broken one! The 333's almost always have the twist shifter. Crack it open and grease it, and it will work like new. If it moves around on the bar, then tighten the set screw on the bottom. Be careful about the ball bearing inside, and don't lose the spring either You can also change grips for a more modern type, if you shorten them.,,,,BD
