Part of the Week! Sturmey Archer Strengthening Pad HSH401
We have the Sturmey Archer Stengthening Pad part HSH401. It goes on the left chain stay of the bike, just under the Brake Arm Clip Assembly (HCB 103 or HCB 104) on the S3C Coaster Brake hub. The third photo shows what it would look like with a brake arm clip on it. I assume it's main function is to distribute the force of that coaster brake arm into a bigger area, reducing paint damage and fatigue on the clip.

Part of the Week! Sturmey Archer Axle Key HSA295
Starting a new segment on the blog, very arcane but totally fun for me.
Just a short post to introduce you to a part that I have available on eBay.
HSA 295, the Sturmey Archer Axle Key!
Nothing much to it. This is the part that accepts the indicator (toggle) chain that you see from outside the hub! Pretty small, super powerful. From some internet sleuthing I've figure out the thread pitch is 3/32 x 48TPI. This is a British Standard Whitworth fine thread. The threads DO NOT match a Fichtel & Sachs indicator chain, but a Sachs indicator would thread in there if you absolutely had to use one. The Fichtel & Sachs key has a 2mm x .25mm thread and is rounded on one side:
See you next week with a new part!
