• Material: Precision-machined 7075 T6 aluminum for an excellent balance of lightness and toughness.
• Mud profile: Teeth specifically shaped to facilitate mud evacuation and limit chain snagging.
• Targeted weight reduction: Strategic cutouts to reduce mass without compromising rigidity.
• Finish: Twin Color hard anodization (blue) that hardens the surface and protects against abrasion while enhancing aesthetics.
• Compatibility: 520 pitch chain, 53 teeth — standard mounting for off-road oriented cross and roadster bikes.

Designed for the terrain, this PBR crown is aimed at MX, SX, and enduro riders seeking a responsive transmission and a lightweight component capable of withstanding muddy conditions. The tooth profile reduces friction with the chain, contributing to smoother transmission and controlled wear. The anodization provides additional resistance to impacts and abrasion while asserting the competitive look of the machine.
