Great brush for getting into the nicks and crannies of your bike after a heavy day of "dirt farming". If you forgot to pack the gaps in your frame with expandable foam this claw / brush is great for cleaning your bike in spaces where water might not do as great a job. It has 3 brushes for cleaning the chain, cassette and sprocket and an integrated scraper for cleaning derailleur pulleys/jockey wheel that always seem to get mucked up. Recommend wearing gloves when using.
The only brush I need to clean the chain and chain rings. Very efficient. Price was right and saves me from having to buy and store multiple items. Brush cleans up easily and after many uses on multiple bikes, looks and feels like new.
