Even with a 300 mm wrench, it was impossible to quickly get out of the free car attached to the car from the beginning, and I needed a force machine power. I wonder if there is a longer wrench (* ^ _ ^ *)
Purchase to exchange MTB 's boss - free rear sprocket. To remove sprocket using this product, you need a monkey or spanner to open more than 32 mm. Since I am troublesome, I will remove the socket on the impact wrench and remove it, but if it is a monkey or a spanner it may not turn unless it is extended by applying a pipe to a handle and applying force. Similar products are available in other companies' products, but there is only SHIMANO genuine, it is strong.
