Mizuno's own USA product page (https://usa.mizuno.com/golf-jpx-one-select-dvr-tensei-blk) states the identical text as the base JPX One: 'Quick Switch Adaptor: 4 degrees of loft adjustability to fine tune trajectory and look.' Equipment press (golfreviewsguide.com) confirms both the standard and Select models share the same up to 4 degree hosel adjustability, not a Select-specific mechanism.
