Road drops. And yeah, I've flipped the stem. I might have to give it another go with the stem flipped upwards. My stem is 100mm and I'm curious to try a 110 or 120 aswell. I will try a 110 stem soon with risers, but that's a different kettle of fish, obviously. (My drops are oversized and I haven't found a longer stem for that to beg, borrow or steal.)
