Found this on a local CL posting and went across town to pick it up. I thought it would work well on one of my Schwinn middleweight bikes. Got there and right away I knew the rim was not a Schwinn. The rim is about 1-1/8" wide (lighweight ?) and it's built with heavy duty spokes. I imagine it came off some X brand tandem. Can anyone identity it? If anyone knows what it is and can use it, send me a PM. Otherwise, I'll relace it to an S-7 rim.
