twisted minis

You only need a pivot joint at the axle if you want to hit sides. Only need 4 total really. Running them at the frame does nothing. Unless you have bag on bar setup, then it just twists the bar, and the bag lowering the lift of the bag.
About $150 or so, with a nicer pivot joint than SD uses. I can also do 1.5" square, turned on its side, like a diamond. I would make bag brackets to go along with it as well that you would just have to position and weld to the bars when you get them.
