A bashguard is a device used on bicycles to protect components, usually the drivetrain, from damage in the case of a strike with an object, whether intentional or in a crash. There are two types, bashrings and bashplates. ==Bashring== In cycling, bashrings are a protective ring, often made of aluminium or polycarbonate, mounted on the outer part of the chainrings on mountain bikes. They are commonly used on downhill and freeride bikes to protect the chain and chainring in cases of it hitting rocks and other obstacles. The position of the chainring makes it particularly susceptible to rock strikes in this kind of riding. They are also often used on trials bikes for a similar purpose–to protect the chain and chainring–although they are often used as a tool to get up and over obstacles. It is for this reason that a lot of bashrings aimed at trials riding have a tooth-like profile. They are also used for landing on a log, so are generally wider than those used for downhill and freeride. Finally, bashrings are used a lot on street bikes, where they are used to protect the chain and chainring when grinding obstacles, and again in the case of a crash. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bashguard」の詳細全文を読む スポンサード リンク
