This product surpassed my expectations.
They are just good quality and fine parts to use in your own bike
If your bike came with the basic type of brake pad where the rubber pad is integrated into the mounting bolt, these are a nice upgrade. The main selling point is that you can replace the rubber pad without disturbing the brake pad adjustment. With the cheaper type, you have to reset the pad placement and angle every time the rubber wears out. Big time saver.
