An in-line skate includes a boot and frame secured to the underside thereof. The frame supports a plurality of rolling wheels in an in-line arrangement. A brake assembly operative upon the rearmost wheel in the in-line skate arrangement includes a wheel having a tire coupled to a rim which in turn is coupled to a bearing. The bearing includes an inner race which receives a channel spacer having a channel formed therein. A first hub securable to the frame is slidably supported within the spacer and a spring is captivated between the hub and the inner race of the bearing to bias the hub upwardly with respect to the remainder of the wheel. A second hub is coupled to the slidable first hub and an attachment is provided to secure the first and second hubs to the frame. As a result, the first and second hubs are secured to the skate frame while the spring and channel spacer allow the wheel to move with respect to the skate frame in response to changes in applied weight.
