Mounts on pickup beds, to a 2x4 for a removable bike carrier for the back of your van or SUV, on the wall in  the garage, to a wood horse or workbench to make a work stand - you get the idea.  Rustproof alloy construction, 3 large holes for flexible and solid mounting, designed for forks with a 100mm QR axle as has been the standard for road and mtn bikes for many years.
