Technical Details and Features
This disc brake caliper features two phenolic pistons, each measuring 48mm in diameter. Phenolic pistons are known for their lightweight and heat-resistant properties, which help minimize brake fade and maintain consistent braking under heavy loads. The inclusion of a bleeder screw simplifies brake system maintenance by allowing efficient removal of air from the brake lines. Note that brake pads are not included with this caliper, so pads must be sourced separately.
