Park Tool CG2 Chain Gang cleaning kit review

A chain cleaner is one of the best things you’ll ever buy if you’re going to own a bike for more than a month, and this kit from Park Tool contains one of the best – the fantastic CM-5.

It features a magnet in the base to attract metal particulates, and replaceable brushes, and it’s a complete doddle to use. It comes with a bottle of CB-2 cleaning fluid and a great brush/scraper – the GSC-1 – for cleaning the rear sprockets.
