Designs for wheels that OEM manufacturers hold/build off of, and add graphics/changes to accommodate a manufacturer/distributors specifications. To be honest.. there probably isn't that big of a difference between a product sold by Reynolds, or another manufacturer who builds a similar product, except with a open mold design.
open mold: any bidder willing to sign a contract with us, we will build the wheels for you.
proprietary: legally (and I mean, "legally" we aren't supposed to make this design except for whoever gave us the specifications.)
