Ahh dropper posts. To me, the single best recent innovation in cycling...although it relies on ideas from the first days of office chairs. When I added a Pivot LES to the fleet, it didn't have provisions for internal routing for dropper post, and I was told "I can't do that on that bike". Well...ahem, I beg to differ. Now I would never encourage anyone to take a drill and file to a brand. new. carbon. frame...but I figured someone smart over designed this frame to have two closely spaced holes, so someone hold my beer...and POOF, dropper post compatible.
