The Various NX2 Support panels are all four way adjustable. So, panel rotation and higback height can be adjusted. The new aluminum offset multi disks offer both width and offest (edge to edge for boot centering) adjustability simulateously and work on 4x4, 3 hole and channel boards (all on one disk). Three binding sizes are available. Medium, Large and XL. If you meant can the heelcup be compressed in/out on the baseplate, I did not see milling for that.
