Here is 4 one off sets we did, these are the only ones.

Set A: Diamond knurls with nub.

Set B: Straight knurls with nub.

Set C: Diamond knurls with dimpled nub.

Set D: Straight knurls with dimpled nub.

These are only in brushed finish, as i don't have a great way to polish down inside yet. I don't have the patience to do it with a dremel, but if you want to, i'll polish as much as i can get done on my wheels.
These are 75.00 shipped. i'll polish what i can of them at no extra charge.
