On gears, it's clear that the involute or cycloid profile are optimal for the teeth on straight gears, but what about designing teeth on a sprocket?

i would start by learning the different between gears, cogwheels, and sprockets.
somewhere in there is the exact answer to your question. you probably wouldn't even have to dive too deep to get it, either.

That's about the best I could find. Nothing as elegant as the property of involute or cycloid teeth smoothly transferring speed from input to output.

Check Shigley's Mechanical Engineering Design for gear design, I'm pretty sure the involute profile is the only one to be used, in very rare cases does any other profile make sense, probably due to the contact area and stress formation in the gear teeth. But I'm no expert on gears, not a sexy topic but very fundamental topic in mechanical engineering that not many people left know much about afaik. I guess automotive engineers dealing with geartrains would be the right people to ask, check forums related to the topic.

Involute gears are just cycloid gears where the radius is infinity.
