Adjustable Dumbbell — SANFAN可调式哑铃 — 三梵

One dumbbell replaces a whole rack. The dial selects the load and the plates stay seated in the cradle, so changing weight between sets is a single turn rather than a walk to the rack. The red locking collar doubles as a visual indicator that the plate is fully engaged. Ships singly or as a pair on a branded cradle.一只替代一整排。旋钮选重，配重片固定在底座内，组间换重只需转一下、不用走去换铃。红色锁扣同时是「已锁定到位」的视觉标识。可单只出货，或配品牌底座成对出货。
