ABSTRACT:
A tension adjustment and retention device for a cam/lever quick-release bicycle axle fastener, having a washer (8) that provides two different thicknesses via two alternate rotational positions. When the cam is loose, rotating the washer 90 degrees with the fingers causes a quick change in clearance between the washer and the drop-out, for removal or mounting of the axle. For axle mounting, a pre-set clamping clearance is restored precisely. A safety interlock slide (60) may optionally be added for automatic, undefeatable, secondary engagement between the axle and safety drop-outs. To remove the wheel, the cam is loosened, washer (8) is rotated to maximize clearance, then the slide is pulled away from the drop-out against a spring. In all embodiments, no tools are needed to quickly remove or re-attach the axle to the drop-outs, and no readjustment of cam tension is needed as with current quick-release adjustment nuts. The safety interlock slide (60) and the two-position washer 8 may be combined as two-position safety interlock slide (70).
