SRAM A2 Automatix; introduction to the internals

Probably the pawl spring, which is like a weak circlip. I remember a mysterious circlip, possibly for extra dirt protection, inside the LH bearing cap of one coaster hub, but that may have been a Sturmey S3C.

I can only think of a few things inside a SRAM hub that could break up and even look like a failed circlip; the ball clip, the pawl spring, and the drag spring.
