Brands:Brand: BOX COMPONENTS
The box two brake post Extenders are the perfect solution for those needing that extra bit of brake pad adjustment without switching frame sizes. NC-machined from 6061-t6 aluminum, box two Extenders easily mount to any frame's existing cantilever brake bosses and provide an additional 16 mm of brake arm positioning.
These brackets are needed to switch wheel sizes and gear ratios.
Can’t use with every brake system. Hard to switch around.
Does what they are supposed to.
