I used to ride clipless on everything, including downhill
it’s only in the last couple of years, and after a knee replacement surgery, that I switched to flats
my cross-country bike is still wearing SPD’s, but my big travel trail bikes are gladly wearing flats still
The only thing I’ve been riding the past couple months is my e-bike though, which is like a monster truck in the trees. Way too much travel and brakes are stupid strong—- I don’t think it will ever see spots
