rear cassete rattle/movement

Mark Alexander

I recently changed my rear cassette from the wheel it was on to a power tap. It's a Sram 10 speed. however, the bottom 5 chainrings are loose. The cap is solid. I have 2 spacers but there is definite space left. I'm not sure what is missing, if anything. Is there a ring that goes on before the solid block of 3 chainring? Could I be missing a spacer?

look along the cogs to see if a spacer is missing.. possibly needs a 3rd spacer behind the cassette
