Key Features
Wind Tunnel Tested (Turbulent Aero): The aerodynamic profile of the 42|49 begins with advanced Computational Fluid Dynamics (CFD). Reserve then utilizes exclusive wind-tunnel testing to simulate real-world, turbulent airflow. The result is a wheelset that meets its performance targets in both sterile environments and unpredictable crosswinds.
Strong AND Light: Designed in Reserve's California composites lab, the carbon fiber layup is rigorously tested using proprietary protocols that mimic real-world impacts and spoke pull-outs. This allows Reserve to define the exact fiber orientation for each rim, maximizing stiffness and strength while keeping rotational weight to an absolute minimum.
