When starting with a new build there are no options for road shifters when you click in the category. The only shifters that come up are flat bar.
Did you look down a few categories to the shift/brake lever category? It sounds like you may have just been looking into the shifter category (where there are only flat bar shifters).
Check it out and let me know if you see them.
Ahh yes, I see my mistake now. Thanks again!
