Had been riding my Giant Defy 2 since 2014, got stolen in 2020. Decided to upgrade. Found a 2015 Cervelo S2 in great condition. Love the bike. Way stiffer, way faster but the handle bar assembly is super uncomfortable when getting into and staying in aero. Considering changing it out for something else (basically a set with longer bar tape area) but I’ve never done that before. Any suggestions on what to look for or big dos and donts of changing up handle bar assemblies (I will have the new ones professionally installed. Not gonna diy that!).
