Weight and Riding Comfort
I like accessories that do not add unnecessary weight to my bike. A plastic chain guard is usually lightweight, which is one reason I prefer it. It should protect the chain without making the bike feel bulky or awkward. In my experience, a lightweight guard keeps the bike comfortable for everyday use.
