This item serves a few purposes.

1. It protects the exposed rear-most horizontal tube of our Big Dummy Frame from dents. Dents that could prevent the use of Wideloader horizontal racks, which would be a real bummer, right?
2. It reshapes the same tubes. The insert is tapered. If you have a dented tube, insert the nose of the plug and tap it into place with a mallet. The frame tube will coldset back to round. Hey presto!
3. The plug is actually two plugs, a left and right side connected by a threaded rod.

Note: Big Dummy Frame Insert will be all silver or a black and silver mix depending on production run.
