The total weight on my test bike with a SRAM Force AXS groupset and Zipp 303S wheels came to 17.1 pounds (without pedals)—a humble weight for an aluminum frame, disc brake-equipped road bike.
There isn't a concession anywhere in the specs; it's pretty rock solid. You could also use the Zipp wheels on a road bike, and they would be at home there with the right tyres, should you wish.
