I used to ride my road bike on dirt roads all the time, would even do laps at the lame
They just used to be called touring bikes. Then everyone decided they needed super stiff super aero race bikes so they could shave 3 seconds off a lap around their gated community. Those things are barley tolerable on pristine asphalt let alone a surface that may have a pebble on it."dirt drops have been a staple of grinding for decades"
They just invented that like 10 years ago as a way to laugh at roadies on dirt roads
