Yeah, definitely for wider tires.

1.25in (32 mm) and 1.5 in (38 mm) tires were pretty common on the "sport touring" category of 10-speeds from the mid-70s bike boom to the early 90s or something like that.

Then marketing decided that everyone, even casual cyclists, should aspire to ride on "racing" road bikes with 23 mm (or even 21 mm) tires, even if the aero and acceleration benefits really didn't make any sense for them.

Really happy that wider tires are making a comeback and that the "gravel" category is in many ways a comeback of sport touring.
