The death of non carbon rim....Carbon is the New King of Wheels

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Are you trying to say that steel is no longer real?

It's true. I saw a lot of rec riders on carbon hoops in San Diego just riding around. Rationally though, I can replace my wheel two or four times for the cost of a carbon rim.

Well since the OP is about carbon wheels and use on one of the roughest and most challenging courses....

those things are heavy but pretty reliable; I had a pair that I used on my bad weather/commuter.

A carbon brake rotor is reinforced carbon-carbon - the stuff on the leading edges of the space shuttle. It's carbon fiber reinforcing a graphite matrix, while most CF is carbon fiber reinforcing an epoxy matrix. They are produced by laying up CF normally, allowing it to cure, then baking it at extremely high temperatures until the existing matrix turns to carbon. It is then injected with acetylene which forms more carbon, filling the voids that form during the previous step. This produces a very strong, very heat resistant, but quite brittle material. But it isn't what your bike is made out of. The production costs also make pro tour bikes look like little red trikes.

P-R is also pancake flat and tends to string out. Riders run 44-46 small chainrings across the board.

Assuming crosswinds are manageable deep wheels are going to be an advantage provided they don't asplode,

Throw an outdated UCI weight limit into the mix and gobs of sponsor money and here we are.

Carbon is the New King of Wheels <--- sure, specially when it is for free. Darn rims are like 700 bucks each (or going chinese no warranty ones) and at those prices there is no way for the average joe to afford them, sure carbon is the new material in wheels, they rock but a good set is like 2000 dollars or more.

At those prices will continue using AL, at least I know that will take like 50 years to eat the braking surface.

^unless you move to Burnaby BC, where you'll wear through 1-2 per season, apparently.

That I wouldn't bet on. There's no real proof at all that will happen in the marketplace. The benefits are just not strong enough in every day use because the average Joe rides on wheels where braking is not the least troubling. The market for road discs won't exist until it's something that most people can see a benefit from.
