Tony G sent me a text, yesterday, and asked if I could take a look at at an old Mongoose he had picked up at the thrift store. I told him, "Sure."
I cleaned it up, overhauled the hubs, and broke loose the stuck stem bolt. It had new tires and tubes on it, so we just aired them up, and took a ride.
The bottom bracket and headset seemed fine, so we just left them alone.
