bought these from....stan, i think? about a year ago, and don't have a need for the rear stand, since it's for double-sided swingarms, and figure it's just better to sell as a set. they work great (see pic below)...i used them in my loft with the SS to tear it down, and they were super-stable. they're pretty much universal, so they should work just fine with other brands. the rear stand has adjustable pegs...so it can accommodate a pretty wide range of applications.

would like $300 for the pair... cyclecat has since gone out of business, so these are getting harder to find. just sayin'....
and FWIW, the rear stand is super easy to use; killer leverage. handles are also removable as well, for longer-term storage.
