Lock washer Sturmey-Archer 13/32" 1.8x9.5mm (HMW515)

This Sturmey-Archer rear axle lock washer helps position a hub-gear axle correctly in the dropout. Its 9.5 mm slot and 1.8 mm thickness allow precise axle spacing adjustment. The washer rests against the dropout and helps prevent the hub from twisting under drive forces.
