Abstract
A roller skate having a wheel support assembly which provides a single device for adjusting the compression within the assembly. The adjustment is accomplished by a cap at the lower end of the assembly which can be rotated to apply the required compression, without the need to loosen any other part of the mechanism. The cap is locked in place after rotation, and is indexed to permit the repeated positioning of the cap.
