These highway pegs utilize our unique offset mount to allow riders a range of adjustment not possible with other clamp-on style highway pegs. The offset can be rotated 360 degrees in a 4" diameter circle to accommodate tall, short, or average height riders. These can be installed on any 1" round tubing (frames or engine guards). But it is important to keep in mind that the footpeg itself will end up perpendicular to the bar to which it is mounted.
