Kommt doch auch immer auf die Fahrweise, das Gesamtgewicht Rad+Fahrer und das Subjektive Empfinden von "hart/weich" an.

Ohne echte Messwerte bringt das alles irgendwie nix.

Zieh dir das mal rein:

During the 303 Roubaix development, we broke the entire bicycle system into component stiffnesses to try and determine the relative contributions of things to ride quality. We were shocked to find that the entire difference between the special, longer wheelbase, layup optimized, cobble specific frame, and the standard road frame (which everybody could tell you was WAY too stiff to ride on the cobbles) equated to a whopping 4psi of tire pressure. Similar result with wheels, turns out that the 32 spoke box section Amrosio rims the teams swore by had about 50% higher vertical stiffness than the 303…yet the riders swore up and down that the 303 was 'too stiff' until we blinded them, at which point the opinions became nearly random with a slight bias toward the carbon wheel as more comfortable, yet with the riders preferring the carbon wheel only willing to proclaim it because they are all certain that it was the aluminum one.
