Roads like this are a big reason why I always recommend wider tires (28mm and above) at lower pressures (50-80psi).

Riding over rough roads on hard, skinny, racing tires (which 95% of bikes seem to have) doesn’t make a lot of sense.

Jan Heine, publisher of Bicycle Quarterly, who I consider an authority on the subject, has done extensive testing of tires at different widths and at different pressures and concluded that wider tires, at lower pressure, can outperform skinny racing tires.

My Guerciotti uses 28mm tires, my Ebisu uses 38mm tires, and I hope to design a future bike around 42mm tires.
