the style of climbing (= moving on rocks, up mountains, or up special walls as a sport) in which climbers use devices and ropes that they bring with them and remove after the climb, rather than using devices that have already been fixed to the rock

Trad climbing is any climbing that involves removable gear. That's by contrast to sport climbing, which uses permanent gear (usually bolts). 传统攀登是任何涉及可拆卸装备的攀登。 这与使用永久性装备（通常是锚栓）的运动攀登形成鲜明对比。

Traditional climbing involves the use of leader-placed/second removed protection. 传统攀登涉及使用先导放置/殿后移除的保护用具。
