Dropper posts on street bikes

Anyone working a dropper submit on their street bike? The professionals are doing it. This yr’s Milan-San Remo. They present the set off and submit at 0:45 however no different point out. I ponder if it is an helpful on a number of the swtichback descents, or perhaps it is extra aero because the super-tuck is outlawed. Additionally, you should definitely watch at 1:40 for a number of seconds of Allephillpe passing via the crew automobiles and at 2:35 when the peleton squeezes via a constricting flip.
