Yea, I should have said "all I can remember in the last few decades". Back when I was wet behind my ears the US bike brands did use steel drop bars which had 7/8" diameters but I hadn't seen any "current/new" for so many years. One more example of recycling old ideas.

How a flat bar shifter or brake lever (or combined unit) will slide past the curves is dependent on the lever's clamp dimensions and/or ability to separate in half. I suggest you be able to confirm this before spending any shipping costs Andy
