Find the path of least resistance. Say goodbye to drag. The DURA-ACE WH-R9370-DISC-TL-R rear disc wheel is designed to deliver ultimate aerodynamic efficiency for time trials and triathlons. It features the DURA-ACE series' most sophisticated rim-shape optimization, adopting an aero profile derived from 30 billion simulations. The full disc structure reduces drag and delivers high efficiency over long distances. When paired with the C99 front, it completes a highly aerodynamic setup for TT and triathlon racing.
