This stem is in great shape, came from a very low mileage 90s Mongoose hybrid bike that spent most of its life in indoor storage and was maybe ridden a few hundred miles at most. Near perfect condition, and comes with internally routed wiring for mounting a cycle computer. The stem was specifically made with a bracket area to mount a computer (see photo 8)

25.4mm clamp
22.2mm steerer shaft
