No sponsors, and rim brakes just went gold and silver at the olympics mens road race. There is no way rim brakes are going anywhere when thats what the best riders in the world prefer to win.
You should go out and buy a Pinarello F too, because that's what the best riders in the world prefer to win :roll:

While it would be great if they stay, there's just no way these teams' bike sponsors don't force them to comply, probably sooner rather than later.

Correct - Silver was on disc brakes. He didn't have a choice, as his sponsor no longer provides a rim brake option. For those athletes whose sponsors still offer both rim and disc (i.e. the gold and bronze medal winners), they elected to ride rim brakes. A reasonable hypothesis is, therefore, that it is all about weight. It is interesting to contemplate the implication if this hypothesis is correct: If the weight limit was, say, 500g less, then there would not be a disc brake to be seen; if it was 500g more, then rim brakes might vanish. At today's arbitrary 6.8kg limit, it's a toss-up. Perhaps that is not a bad thing - it makes for interesting choices!

Said it multiples times, weight is only one aspect, overall performance (measured or perceived) is the real driver (aero, responsiveness feel, weight…). Few teams did specific work comparing both.

The new female Olympic champion on the road, who can completely choose her equipment because she has no pro contract, was on discs ;)

Legitimate question - Is the UCI limit for Women's road bikes also 6.8kg? If that is true, and assuming she was riding a smaller size, disc brakes may not have been any weight penalty for her, whereas they may be for riders of larger sizes. I will say she had some interesting choices in gear, riding a Shimano groupset with SRAM crank, and either Continental tubeless or clinchers - it was hard to tell, but I'm pretty sure they wern't tubs. I sort of like seeing what gear people use when they are not being paid to use it or told what to use by their employer (team).

Prog used both Rim and Disc brakes during the Tour. He used disc brakes on the wet days including Stage 8 where he gained a huge lead, and he used rim brakes during the dry mountain stages. I think this proves that there are advantages to each brake type and he used both to his advantage. If Keisenhofer's disc brake bike could come in at 6.8kg that eliminates one of the biggest drawbacks of disc brakes - the weight, whereas Prog had a reported 400g weight increase with disc's over rim.

Richard Carapaz is 5'7" tall. Anna Kiesenhofer is 5' 5" tall. If Kiesenhofer is on a smaller frame, it is likely only one size smaller than Carapaz. Even then, frame weight doesn't vary much as the size changes.

Maybe not relevant to the conversation, but she also used the Farsports F1 integrated Cockpit. Really interesting in my opinion.

Especially since the Scott Addict RC Pro bike she started with had an integrated cockpit already, and I would assume any upgrade(s) she funded herslef, so she must think they are worthwile.

It could be that there was a weight savings for those riders to ride rim brakes, at least that would be my assumption.

If the UCI was to lower the 6.8kg weight limit to say 5.8kg, rim brakes might have a revival, but as the major brands start to get disc brake bikes down to 6.8kg disc will likely completely take over the pro peleton in a few years. Each brake type has it's advantages, but brands seem to want to sell disc brake bikes, so that's what they push.
