Good point however the data sourced is through year end 2019 sales, prior to the Covid boom.

As gravel grows more and more inclusive we will see continued growth in aluminium sales relative to carbon. 2019 was a landmark year in that we saw several major companies make shift towards creating a true market for non-racing enthusiasts and also components starting to be manufactured specifically for "gravel" riding.

Here's an interesting piece from earlier this year that argues for the positive impact the genre has had on the industry and why it is likely to continue its boom even after the Covid. As more and more regular folks take to it and the Fred factor lowers there will be a spike in metal and steel bikes.

Also more threaded BB's.

Companies like Trek that have been exploiting the ignorance of most people (Selling $2,000 bikes with lousy wheels with non-self serviceable hubs, press-fit BB's, road gearing and unable to fit fatter tires) will be forced to actually change and make bikes to meet the demand of educated gravel consumers.

There are a lot more miles of "gravel" roads out there in the public domain than there are single tracks and the segment is set to explode. With the new aluminium technologies and their success in racing its gonna keep that pendulum swinging in the same direction and continue to drive sales.
