Yeah, apparently the powermeter/chainring assembly is about $820 - that's a chunk of change for changing chainring size.

And what's up with all the cassettes starting with 10 tooth sprockets. Smaller sprockets have greater energy losses, so you're leaving some energy behind when you use these cassettes.
