Box Two™ Brake Post Extenders are the perfect solution for those riders needing extra brake pad adjustment without switching frame sizes.
CNC-machined from 6061-T6 aluminium, Box Two™ Brake Post Extenders easily mount to any frame's existing cantilever brake bosses. They provide an additional 16 mm of brake arm positioning.
Typically, they are most useful when a rider transitions from one wheel size to the next (i.e., 451 to 406). Depending on your application, they can be mounted in either one of two positions - above the frame's v-brake mounts or below.
