A brass adapter (black anodized) attaches to the BRX70/BRX90 knuckle and the brass caliper attaches to the brass adapter. On the front, it can take up to two calipers on each adapter (for weight adjustments).

The stainless steel brake disc is machined together with a 12mm standard hex. The hex uses a drive pin and has two set screws to lock down the drive shaft securely.
