Probably depends on when they were made. I ordered mine December of 2021, they arrived last week. I had the option to choose SS lines but they come stock with the kevlar Kevlar reinforced high-pressure line.
Weird, I would have ordered mine back in March of 2021. And I received them in October of 2022. Mine came stock with the black rubber coated SS braided lines. I ordered some of the kevlar line knowing the thicker braided line wouldn’t fit in my Orbea Wild frame.
