Carbon Steerer vs Aluminum

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

Is this sarcasm? For a 70 kg rider, we're talking rim deflection on the order of 0.001".

That was the guy whose report I quoted saying that, not me. John Allen, who took over Sheldon Brown's page, immediately follows that guy's statement with one saying that no one can feel that difference through the tire.

I don't know why some people still believe that variations in vertical stiffness in built wheels are perceptible through the tire, but people believe all sorts of things that make no sense to me.

Placebo is very strong.

It's tyres, and potentially seatpost, potentially bars, maybe a little fork blade or even steerer.

A decent length of light carbon seatpost can feel like two tyre sizes worth of ride comfort. Flexy aero carbon bars can also make a surprising amount of difference.

Fork blade flex, probably capable of taking the edge off sharp impacts, and absorbing a bit of high frequency stuff. The material is less important than the design. Steerers flex too, not so much tapered ones. Size of effect probably half an order of magnitude below the slight effect of blade flex; the headset bearings would notice it more than you would.
​​​​
Steerer flex is definitely a thing, but mostly just in the context of heavy braking.
