Abstract
A quick release skewer assembly for use in mounting a wheel to wheel supporting fork includes a camming lever that is pivotally coupled to the skewer for pivoting relative to the skewer between lever closed and lever open positions. With the skewer properly tightened on the fork, pivoting the lever to the lever closed position clamps the wheel to the fork with a clamping force. A biasing member coupled to the skewer and to the fork applies a biasing force that biases the lever toward the lever open position. When the skewer is insufficiently tightened, the biasing force moves the lever to a bias rest position between the lever closed and open positions. The positioning of the lever in the bias rest position provides a visual alert to an individual using a vehicle, such as a bicycle, that the wheel is insufficiently tightened.
