So these actually have more contact area on the leg and top tube, effectively making them wider. The middle tube loses out a bit but really it is over kill. I had another on ready to go super minimal and it worked great, but I new it would not be well received. So this is the middle of the road for me.
That roller hitting is exactly why I said this should gain 5mm on each end if not more. I got the plastic out of the way of the rollers. Over all smaller footprint, I hope, when I put one together I will know for sure.
The other one was fine but I feel this makes the leg connection much better and should keep all 3 axis at 90 degrees from each other much better.
