All hardware are designed and made. RB uses M6 Allen (vs. Brembo OE M5 w/H head) for extra strength and easy maintenance.
RB hats are machined from forged 6061-T6 aluminum alloy (vs. extruded) for higher in strength and structure consistency.
Our hat design is programmed to generate "STEPS" to increase the heat path, which provides more cooling surface and extend the heat transfer time to the hub bearing from the disc - A True HAT that's more efficient in cooling, unlike competitions' design with a tapered contour "BELL" which has more immediate heat transfer with less cooling area.
ALL RB rotor hats are made with M4x0.7 thread holes for balancing provision even our individual disc is dynamically balanced with weight correction.
