Check out Ican wheels. High quality with tons of good reviews for inexpensive Chinese carbon. They have a gravel wheel they’ll set up with the hub spacing you need for the creo 1 - just email them with your needs. I have a set of aero plus 40’s for my BMC that I’m very happy with. They were $700 including shipping and arrived within a week from their U.S. warehouse.
Keep in mind that if you want to keep your old wheels intact you’ll need two rotors, a cassette, and two lockrings, one of which should be the specialized ring with the speed sensor magnet. Otherwise you can switch those parts over to the new wheels if you want.
