PRO BIKE TOOL Cassette Lock Ring Tool for Shimano MF Series & Campagnolo Cassettes for Bicycle Repair & Maintenance – for Road or Mountain Bikesaa
If this was for a Shimano well...it does not fit what so ever. I call this a monkey wrench... useless.
The cassette lock remover tool worked great. The tool is simple and easy to use. But if you're buying this to save some money on bike repair yourself it comes with instructions. This was a good purchase for me, it has already saved me $200 in bike repairs.
