These essential washer incorporate serrations to keep the axle from slipping forward, and also features tabs that keep the axle from rotating in the frame due to pedaling torque.
If you're using a Sturmey-Archer hub on a newer frame made for a wider axle, you need the HMW494 with 9.5 mm tabs instead.
The HMW155 with 7.9 mm tabs fits the narrow axle slots of bikes originally intended for Sturmey-Archer hubs.
This is the only place I can find these washers yes!!!!

Just the thing you need (the only option really) to keep that old sturmey running on a modern frame. BUT, the metal is brittle. one of these snapped right in half on me. so, make sure your dropouts are perfectly aligned and don't let any sort of lockwasher touch these as they can scratch and start a fracture or unevenly stress these wimpy little guys.
