A racing wheel for a vehicle such as a bicycle. The wheel includes a rotationally stationary inner component connectable to the bicycle, a rotatable outer hoop having a bearing engaging surface, a ground engaging tread disposed on the outer hoop, and bearings mounted on the inner component to be rotationally stationary therewith. The bearings each include a support surface contoured to operatively engage the outer hoop bearing engaging surface such that the outer hoop is axially and radially supported relative to the inner component to allow rotation therebetween. The bearings are positioned around the inner component at particularly selected locations to achieve high wheel performance.
