Just say'n!
As long as we are being pedantic, I object to that definition of sprocket. That is the description of a sprocket tooth, not a sprocket. Elsewhere (wikipedia, for example) points out that a tooth on a sprocket is also called a cog so that description meets the meaning of cog. And, besides that, as long as we're being pedantic, it should be "each [...] engages with the links of a chain[...]"
But, people call sprockets cogs and sometimes it sounds/feels better to write sentences in which the subject and verb do not agree in number. Just the other day I learned that in today's world, the proper singular of dice is dice. I'll get over it.
Many years ago I was informed of "Skit's law" which states that it is nearly impossible to identify and point out a minor mistake in writing or usage without making at least a minor mistake while doing it. Usually I obey Skit's law, no matter how I try to avoid it.
