The brush works well to clean the sprockets cassette, especially not tear my cloth. Spray with short Entfettungspray and then clean with the brush pinion .... works perfectly.
More to this brush also can not, for about 5 EUR better every time to get as a new flap because it was torn from the tip sprocket.
The "two-pronged end" fits into a chain link and thus is suitable for cleaning the same.
