A few of the center racks appeared and we can not figure out what they fit. Perhaps you can solve the mystery. They are well made and could easily be adapted to fit a variety of bikes. If you figure it out, be sure to let us know!
Lower mount is 120mm apart and sits 58mm below the rack. Upper mount is 125mm apart.
These are older inventory so there may be minor marks in the paint from years of storage. Otherwise, they're in great shape!
