New 2026 line, researched from scratch. Mizuno's own USA product page (https://usa.mizuno.com/golf-jpx-one-dvr-tensei-blk) states verbatim: "Quick Switch Adaptor: 4 degrees of loft adjustability to fine tune trajectory and look," same naming used for every prior generation in this dataset. Golf Club Trader's fits-list (https://www.thegolfclubtrader.com/products/new-2019-mizuno-st190-st-gt180-jpx900-driver-adapter-sleeve-oem-quality-335-rh) groups "JPX One" under the same SKU as ST-Max 230/ST-G/ST-Z 230/ST-X 230/ST-Z 220/ST-X 220/ST200/ST190/GT180/JPX900. The already-cited Adore Golf Grips listing (referenced in mizuno-quick-switch-st200's curation_notes) also lists "JPX ONE" alongside ST-MAX/ST-G/ST-Z/ST-X/ST200/ST190 in one fits statement. Classified to the nearest predecessor registered generation, mizuno-quick-switch-230 (2023), not a new adapter, since no evidence of a distinct non-interchanging new hosel was found; equipment press (golfreviewsguide.com/mizuno-jpx-one-drivers/) independently confirms "up to four degrees of adjustability from the hosel."
