THIS IS SPECIFICALLY ABOUT A TIME TRIAL FRAME
There is a chance riders on this stage use time trial bikes for part of the stage and road bikes for the other part ("bike change"). If the race leader uses a yellow road bike but a 'normal' TT bike, that would not resolve Yes.
They have to use a TT specific frame (with aero extensions, etc.) that is blatantly and obviously "painted yellow". Not just stickers, not just a yellow fork or something. This has to be very obviously a race leaders yellow jersey TT bike.
The reason I'm asking is because it is common for a race leader with a consolidated lead to use a yellow road bike in the final stage or sometimes the last few stages. But will the team of the leader have the resources to put together a race leader yellow TT bike!?!?!?
(It has to be definitively different from any bike they used on Stage 7.)
Does it depend on which rider it is?
I looked on Getty Images for any images of Pogacar on today's TT bike that could show part of the bike PAINTED yellow. I see:
His name sticker has his name in yellow. This is a sticker, not paint:
The downtube says COLNAGO in yellow. Ronan Mc Laughlin of Escape Collective reported the bike was normal, with "decals" and a yellow saddle. This looks like decals to me, not yellow paint:

HOWEVER, there really is no argument at all about whether this is "paint" or "stickers", because it's the same bike he used on Stage 7, which is specifically disqualified in the criteria:
(It has to be definitively different from any bike they used on Stage 7.)
As a result, this is resolving No.
