Mega useful...

I've put it through the wringer

I have cleaned my cassette on my Specialized and i was amazed how easy it was... simple tool for a job... best 6 dollars spent on tools... clean spaces between cogs... cassette was shine after easy clean up... after dirt has gone away all the reading on the cassette became visible... definitely must have tool for a MTB...
