What are the Campagnolo chorus chainring sizes?

According to Campagnolo, these smaller chainring sizes (there’s no 53/39) along with a choice of 11-29,11-32 or 11-34 cassette makes Chorus the ideal groupset for those wanting a multi-purpose cycling experience – with the 48/32 clearly aimed at the burgeoning gravel market.
