If you have the carbon SI crank then it’s BB30. There were plenty of BB30 caad8s, 7s, 6s.
Eyeballing the bottom bracket shell from below if you know what you are looking for will tell you. Or just pop the crank arm off and measure the spindle dia- IIRC the carbon SI crank has captive bolts. It’s one of the few good things about them :)
Howard, you are right, it is BB30 (confirmed by a mechanic). There are not many available cranksets for BB30 here, but I managed to find a FSA Energy crankset with BB for a reasonable price (85€).
