These bullmoose bars came from a 1985 Specialized Rockhopper and I believe were original to the bike. They are in great shape, some very minor surface rust on the inside the main joint (see photo 7), can probably be polished away if you can reach it (I couldn't). I can't make out any branding, may be a Nitto but maybe not. The chrome finish is laid on a little thick and you can barely make out even the "Cr-Mo" stamp. This is the model with the built-in cable stop.
130mm stem length (center of the steerer bolt to center of the bar)
62cm wide
22.2mm steerer shaft, made for a 1" headset
Feel free to message me with any additional questions.
