Sturmey-Archer Cone Lock Washer (right side)

This essential washer incorporates two tabs that secure the wench flats of the right side cone, so that it will stay in adjustment.

The right cone adjustment is quite critical. With the left cone slack, the right one should be tightened finger tight, then backed off 1/2 turn, plus as much more as is needed to get the flats to line up with this washer's tabs.
