a lot of steel frames are stiffer and heavier than they were due to the introduction of the CEN standards i believe.
This +1, and some are just stiff anyway.
I’d rather ride an aluminium frame, I just prefer the imediacy of them and the lack of mass. There’s a connected feeling you get with a very stiff lightweight aluminum XC frame that no ammount of “steel is real” compliance can replace.
But I’d rather own a steel frame as they put up with the abuse, theres a big dent in the top tube, plenty of paint missing, it gets locked to railings, and rarely cleaned, but I’d not question it’s strength. Whereas aluminium frames I’ve worn through chainstays!
There are tough aluminium frames too, but they’re further between.
