It's called a dork disc because you're a real dork if you take it off and think those 15 grams are going make you faster
Flamesuit on!
I was gonna say, it appears to me that the "dork disc" is there for a good reason.
I remember when having a chain guard was considered super-dorky. Having had a pantleg caught in the chain a few times when riding in cooler weather, I guess nowadays I'd just prefer to be a dork.
