自行车头盔

马克·i·利维(Marc I. Leavey)医学博士说,如果你是自行车爱好者,就不要冒险去买二手头盔他是马里兰州巴尔的摩市慈悲医疗中心(Mercy Medical Center)的内科医生。旧货出售可能在几个方面有害。Leavey说,这款车可能是老款,没有新款车的安全性能,甚至有可能被召回。在这种情况下,一个全新的项目,在未知的阶段,可能是一个危险。正常的磨损可能削弱了肩带或扣环,或可能丢失了一些部件,如紧固件或调整器。如果物品发生了任何事故,即使没有明显损坏,设计用来吸收冲击力的部件也可能被严重削弱,使你处于危险之中。

If you’re a fan of cycling, don’t take a chance on buying a used helmet, says Marc I. Leavey, M.D., an internist at Mercy Medical Center in Baltimore, Maryland. “A garage sale purchase may be harmful in several ways.” The item may be an older model, without the safety features of a newer one, or even have been subject to a recall, says Leavey. “In such cases, a brand new item, still in the box, may be a hazard.” Normal wear and tear may have weakened straps or clasps, or it may be missing some parts, such as fasteners or adjusters. And if the item was involved in any kind of accident, even without obvious damage, parts of the device that are designed to absorb impact may be significantly weakened, putting you at risk.
