An effective brush, equipped with sturdy nylon bristles designed for cleaning chains, chainrings and removing dirt between the cassette cogs. The main bristles are densely packed and ideal for cleaning the chain, chainrings and cog teeth. On the tip of the brush harder bristles can be used between the sprockets for deeper cleaning. For larger spaces between cogs (up to 10 speed) the curved handle with serrated teeth can be used to remove mud, grass or debris.
