Is the cycling community just being paranoid about chain drops or are they actually a common issue that warrants the use of a chain guide? It seems like every other rider is using one of these devices, but are they truly necessary or just a solution to a problem that doesnt exist? Is the risk of a chain drop really that high, or are we just coddling our bikes with unnecessary accessories? And what about the added weight and potential for increased friction, are they really worth the supposed benefits of a chain guide? Do riders who use them actually experience fewer chain drops or is it just a psychological comfort?
