52 ASC Carbon Extensions 400mm Bar Ends and they're not indexed (smoothOverview When designing these extensions we wanted to utilize carbon fibers' natural ability to be shaped into an aerodynamic form while still providing a good amount of strength and rigidity, hence ASC stands for Aero Shaped Carbon. The 52 ASC follows on from our hugely popular first Aero Shaped Carbon extension (The 43 ASC) with increased grip angle. The front section (from the wrist fin forward) has been angled up by 9 degrees to give a 52 degree
