108-millimeter P-1 brake arms are cold forged from 6061-T6 aluminum. Cold forging produces the strongest, lightest weight and most durable bicycle parts.
Both sizes feature 35 millimeters of vertical brake pad adjustment—about 30 percent more adjustability than most linear-pull brakes.
P-1 brakes have a unique look that results in a design that is lightweight yet provides maximum braking power.
Included are new, proprietary, two-tone, dual-compound, B-2 Air Flow, one-piece brake shoes developed by Promax specifically for the P-1 brakes
