Started trying to type a description of how the ones I chose are and what they do. But didn't think it'd make sense without seeing it also. So just grabbed the camera and took some pics real quick. Here ya go....
These are Kuryakyn parts 4526 (mounts) and 4445 (pegs). I looked at everything I could find before picking these pegs and mounts. The arm is infinitely adjustable in the 360 degree arc. The arm has a little allen set screw that works as an adjustment for the peg (the peg rests against the set screw as it folds away from you). This allows a lot of adjustment to bring the peg closer to or farther away from you. This also effectively adjusts the angle at which your foot is resting. This works very well in conjunction with the ability to swing the arm itself closer to or farther away from you by rotating the arm itself on the other axis.
I chose the pegs with the stirrups just for the extra position to rest on long rides. Can never have too many different ways to stretch out. I'm 5'9" and positioned as these are I can lay my foot all the way on top, directly against the peg, or against the peg and stirrup. Can also keep my heel on the footboards and just rest my foot outboard against the pegs or the stirrups. The stirrups work very easily and are a snap to kick up or down while going down the road. You can do it without looking once you've done it a time or two. Also, the ways these are mounted I never rub the lowers with a boot or pant.
While I think most all pegs aren't the best looking addition in the world I wouldn't take a trip without them. And these don't look too awful; for a peg.
