This whole hole-less rim thingy is interesting to me. Is the benefit of this to save weight by not having to have a tubeless rim strip? I've got to wonder which weighs less... a hole-less rim or a holed-rim with tubeless tape (the holes would save weight 'cause holes are super light ). If the weight turns out to be about the same, I guess I'd opt for holes just to avoid the difficulty of working on the wheel (should that ever need to happen, which it may not.)
