I knew it was for the front, but I wanted to use it at the rear and bought it.
It would be appreciated if you could prepare for a short rear shaft or make it longer for threading so that it could be diverted to the rear.
Although I bought it for attaching to the 27-inch city cycle, although I barely reach it, the brake shoe felt coming in contact with the horn instead of the surface, so I abandoned the installation and it was inevitable that I installed it in the 24-inch city cycle . The cross section of the brake shoe of this product has a trapezoidal shape with a long lower side, and I thought there is good or bad compatibility depending on the shape of the rim cross section. Also, since the brake arches are built according to the default brake shoe (trapezoidal section), I felt that compatibility would be worse if you use other company's brake shoes.
The price is neither high nor cheap, the product is neither impossible nor impossible, and the body is aluminum but the spring is steel? As it looks like it will not be released from rust ... When I apply the brake the body will also deflect back and forth together so I think about the mechanical strength, still meaning that it is with a Japanese manufacturer, so it also contains the meaning of cheering If it is the same price zone we recommend this.
