Cooling was a major design goal for BOX, and they've machined out all the nooks and crannies possible to allow air to flow through and around the brake, which will help it cool faster and maintain braking power better. The brake pads also use two distinct compounds, separated in the middle by an air channel. Pad removal is tool-free. To bleed the system, you'll use a syringe to push fluid up from the bottom.
