2.0 out of 5 stars Bike chain cassette brush, April 17, 2009

I purchased this brush to clean our bicycle chain and cassette. While it is good for digging out dirt inside the cassette with the plastic end, the brush did not stand up too well after about 4 uses. I used bicycle recommended degreaser first to loosen the dirt and grime on the cassette and then the brush to remove it. While some brush hairs fell out, the brush lost shape. I went back to an old tooth brush, much more economical.

For the price for a brush probably made in China for 50 cents this brush could be said to be over priced.

Park Tools may want to rethink the marketing of this brush as I have some of their tools and have no complaint.

The concept of the tool is great, but the first time I used the tool it broke. The brush bristles are held in poorly by a small plastic piece which snapped when very little pressure was applied.

1.0 out of 5 stars Cheap plastic, September 16, 2011

The problem with the design is that the brush head is held in by 2 thin plastic tabs, which are part of the one piece plastic handle. One of the plastic tabs broke on the very first use. This lets the brush head slide out of the handle and makes it useless. Cheaply made brush. It will definitely break sooner rather than later.
