Review on Park Tool CG 2 4 Bicycle Cleaning by Thong Lopez

This chain cleaner has been thought through down to the smallest detail. It basically makes cleaning your chain a lot easier. My chain has never been cleaned so it was quite dirty. I don't have a bike stand, so I turn the bike upside down and lean against the saddle and handlebars. That made the process difficult. I had a little problem keeping the level of the instrument while pedaling. The tool has a reversible handle, clips to hold the top and bottom together and all brushes can be removed for cleaning or replacement. I highly recommend it. It will probably work even better if you clean the chain frequently.
