7/8" x 6" knurled adapter tube can be clamped in standard handlebar clamps. This allows you to clamp Rox Height Adjustable Risers to portion of tube that is sticking out beyond original clamps. The bars you are clamping must be STRAIGHT bars or have a clamping area 2" wider than your original clamps. Most OEM bars with a bend or rise in them, bend up as soon as the exit the original clamps. The Height Adjustable Risers can not be clamped on this bend.
