• Thanks for the suggestion. Is the logic behind this that they are essentially the same rim but without the machined sidewall? Would that not have a negative effect on breaking performance?

    It probably has a positive effect of breaking performance, since none of the original extrusion is machined away. Braking performance is barely affected, but you do have to scrub flakes of alumina out of your pads and the rims quickly start to look like machined ones as the soft anodising wears off.
