In all seriousness I don't actually believe this to be the case. would love to have an older cannondale tourer. As of now I use a 1990 cannondale crit bike for light summer tours and find it pretty comfortable on long days, even with 25mm tires. And if I ever do any off road my old Gary Fischer kia tia would be the one I take. As long as it doesn't have thru axles aluminum should be ok.
but the main road tourers I grab are steel.
