Review on Park Tool Unisexs GSC 3 Cleaning by Paul Varnado

Revainrating 4 out of 5

useful cleaning tool

I used this brush to remove sand from the rear cassette sprockets. Worked fine for that. I also removed sand particles from the rear derailleur. These are difficult areas to clean, this brush will be one of my main tools to keep them clean. (Not perfect, but works well. I hold the brush vertically behind the rear sprockets and SLOWLY rotate the handle.)

Pros
  • Dope ๐Ÿ”ฅ
Cons
  • Dear
