The Jongbloed (pronounced "Young Blood") JRW 305 Aero is a forged, lightweight, 3-piece, racing design.

The 305 Aero 's functional fan blade design provides exceptional brake/bearing cooling from air movement as the wheel rotates. The wheel also has exceptional thermal convection properties and acts as a heat sink drawing the heat away from the rotor and bearings.
