Profile Design 52 ASC Carbon Extensions Size:400mm IP67 ratingWhen 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.
