The Box Three brake arms are cold forged and CNC-machined from 6061-T6 aluminum and feature 35 millimetres of vertical brake pad adjustment—more than most linear-pull brakes. Cold forging produces the strongest, stiffest, lightest weight and most durable bicycle parts. Other features include sealed bushings, stainless steel hardware, a flexible cable noodle and streamlined cable fixing point. Colour: Black, Red, Blue, Silver; Size: 85mm, 108mm
