You're okay but that's not the best setup in the front. #drag. Put a 23 on the front and keep the 25's for the rear. [emoji41]

I suspect this may not be true but it's an un-provable hypothesis wither way as it depends on how you are defining "aero".
Wider tyres are only *more aero* (whatever that actually means in the real world) as an interactive component with a suitably shaped rim, according to all of the data that I have reviewed.
The problem is that we don't have a standard definition for "more aero" or even "less aero" - we don't have parameters for the frame, wheels, legs or any other part of the rider-wheel system standardised, we don't have a standard set of yaw angles or air speeds and last we don't have standard cadence rate for our yet to be defined legs making a mess of that unknown airspeed and it's un-defined yaw angle. And for uncertainty factors in trying to produce an accurate, meaningful, quantitative measurement, that is just for starters ...
In a wind tunnel, in a non-revolving test factoring all of the above out, it'll still depend on the precise rim shape and I have never seen that data for a Campagnolo Bora in public-land - not that I have looked that hard because it would be real-world irrelevant anyway (with apologies to all the would-be aerodynamics weenies out there ...)
