Meh. Most of the marketing copy on "gravel" bikes sounds exactly like the copy on touring bikes.
They just removed the parts about carrying lots of stuff, and probably the braze-ons too, because they're not "cool".
"Gravel" was also an opportunity to make what are essentially touring rigs out of CF, which previously had no market, because touring cyclists all want steel.
But if, years ago, you bought a Surly LHT, or a Trek 520, or a Bianchi volpe , or something similar, then you got a "gravel" bike prior to the marketing.
