Quality
It's a high quality brush for cleaning your drive train. It's Park Tool so yeah it's an expensive brush but if you know your cycling gear then you know Park Tool stands for quality, and it is certainly that. You don't buy Park Tool then complain it's overpriced. You really do get what you pay for.

Just What I Needed
An absolute must when cleaning chain and sprockets, firm enough to remove all the stuff from them but supple enough to move into all the gaps. My chain has never been cleaner.

Solid as they come
Really solid stumpy brush. Bristles are a good strong nylon and the shape of the brush fits the cassette well.

Better using a washing up brush
Now we know ParkTools are very good, but not this brush. i'm getting better results by using a washing up brush at a tenth of the price

Sehr gutes Tool zum reinigen des Zahnkranzes. Wirkt sehr wertig und hält sicher lang, da die Borsten aus einem starken Material sind. Ich würde das Tool wieder kaufen.

La spazzola risulta efficace per la pulizia di pacco pignoni, guarnitura e in generale per parti del cambio. Acquistata su werehouse ha un prezzo accettabile altrimenti il prezzo è eccessivo.
