One-way adjustment of the mummy-chan's front brake (single bipot), with a normal wrench, does not go well because the handle hits the mounting hardware of the shopping basket. This wrench is inserted from the side and it is very convenient because it can fix the bracket of the brake. If you get used to it you can adjust center by one shot. The size of the bracket adjustment bracket differs depending on the manufacturer, 12 mm, 13 mm, 14 mm, etc. There are various kinds. This product does not support 14 mm. I think that it is very convenient if there is an offset wrench that is compatible with all sizes with one book.
I tried to purchase it because it seems to be a tool to be used for adjusting the brake of Mammaari. It is a price which can be purchased even in terms of price. It is not a tool to try with exhaustion frequency but once you purchase it will be a life.
