Make sure the it’s the lock ring is 41mm before buying
This isn’t a review. Amazon’s costumer service bot sucks so I’ll just make a public post. I needed a lock ring, the LRT-4 is the tool amazon paired with the lock ring I needed. Unfortunately, the lock ring needed a 68mm bb tool (that I already have), but the LRT-4 is for 41mm lock rings. Amazon need to fix there recomendations.

The fix to a long project
Holy heck. Getting this tool was a saga. I bought 4 different tools for my project when I needed one. I needed to get a shimano center lock ring off the chainring of my Canyon Torque e bike. This center lock ring is not the same size as the center lock rings for hub mounted brakes! It’s a 16 tooth but not the same diameter. Additionally, it had to slide over the spindle. I had to take it to a shop, make them put the socket on, and then grab that tools part number. I got the park tool 36mm crow foot wrench since I wanted to do it right. My tools all came together, and I had the part off in less than 3 minutes. I returned two items I purchased on Amazon during this cluster which is why we pay for prime. All around satisfied customer and happy to be done with this project.

Alternativa a Shimano TL-FC430
Alternativa a la herramienta Shimano TL-FC430 para sacar el anillo que coge el plato en un motor shimano EP600 / EP800 (no 8000). Probado en Orbea Rise 2024

Works as expected.
Works as needed easy to use, and solution for the right torque is also easy. Little bit pricey.
