Review on Impressive ISOAR Front Chainring Direct Mount Tool for Effortless Installation 🔧 and Removal of Chainring Lock Ring - Compatible with Shimano M7100, M8100, M9100 by Matt Kucrud

Great tool! I love the o-ring that sits tight on the spindle and being able to use a BBT-9 tool to turn this tool is perfect. However, removing the tool can be a little tricky. I had to use a thin edge tool to separate this tool from the chainring. It wasn't a huge effort, it was just impossible to grab this tool and move it after tightening the sprocket. Not painful at all, but it would be nice to have an extra feature built in to make it easier to retrieve the tool after tightening. Overall, however, I am very satisfied with this product.
