There is no deliberate ignorance -- it's my experience.

Is a Colnago disc bike like they ride 6.8kg?

It just shows that disc brakes are not a guarantee of winning.

Ive said it many times but IMO pro cyclists are not the ones who need disc brakes, its us punters.

A GCN review of the 2020 Colnago V3r (Davide Formolo's) rim brake bike was 6.9kg.
That is why I doubt it.

Cervelo R5 Disc is 1/2 pound more than the rim version in DA.

Twenty seconds from mechanic arrival to rider departure is a few seconds longer than the fastest rim brake wheel changes, particularly if we look back to the days when lawyer tabs were filed off. Back then, a very good mechanic could swap a wheel and push their rider off in less than ten seconds. But with lawyer tabs in place, the gap narrows considerably – in fact, a few mechanics have told me that a disc wheel change with an impact driver can be faster.
In the end, thanks to a bit of mechanization, it’s largely a wash. There’s more time to be gained or lost in the skill of the mechanic than in the type of axle and brake used by the rider.

The bikes that they ride in the tour are rarely exactly the same stock as the OEM versions of the bikes sold retail. For one thing, the wheels are almost always different.

My next frame is going to be a rim brake only because it is a warranty replacement and Trek won’t replace it with the disc frame. Of course, all those guys descend better than I do so it is probably less critical.

In the 2019 Cycle Oregon, they had several riders with heat damaged carbon rims from one of the descents between Steamboat and Culp Creek Oregon.
Of course Cycle Oregon riders may use their brakes very differently than pro racers.

It's easy to get under the UCI minimum on a ready to ride bike shaped object.

Have fun riding your BSO buddy. You wait till starva hears what you've been up to.

It was also quite interesting that they used disc brakes on the earlier wet mountain stages. I can only think they would do this if the braking performance was superior. Otherwise why not use lighter rim brakes for ALL the big mountain stages?
So what does this mean from an average rider's perspective? Not much other than high-end rim brakes are still pretty effective and super-light, but disc brakes work more consistently in a wider range of conditions. Changing wheels is trivially easy on both when every last second doesn't count. I personally prefer through axles for their easy self-alignment.
