FWIW here is Hirschi spinning around 120 rpm (for short periods of time). He's not asking for a bigger chainring. https://youtu.be/Uot32nsQNn0
And here's a good clip explaining why pros don't bother pedaling much at that point anyway. https://youtu.be/zojjIghKQoM

But I digress, if someone wants to pedal 60 rpm on the flats, let them throw a 53 on. As long as they have healthy joints and aren't trying to win a race, it should be fine.
