Unfortunately they don't fit on the deep 6 stem. They are 1" and the deep 6 takes at least 1 1/8" stem. I had to mock them up with a bunch of cardboard stuffed to shim them. They almost looked ok on my kids bmx. I can mount them back to the bmx if you would like. I'll sell you these cheap if you like them. They look terrible on the Deep 6 though.
