Park Tool Bike Cleaning Brush Set - BCB-4.2 $19.76
Ditch the toothbrushes.
Is your cleaning "kit" still limited to a few decade-old shop rags and a rotation of retired toothbrushes? You can do better, and your bike deserves it. The Park Tool Bike Cleaning Brush Set (or BCB-4.2) is made up of four brushes: one soft bristle soaping brush, one frame cleaning dual-headed sponge/bristle brush, one tapered detailing brush, and one gear cleaning brush, aka Park Tool's shop favorite GSC-1 brush. Each is designed for a specific area of the bike so that no spot is left unscrubbed, from the tight spaces between cassette cogs to the nooks of frames, hubs, and forks. Ergonomic handles, dual-density grips, and solid construction mean they won't just make the job easier, they'll do it better, and they'll last through many of them.
