Why road bike use dual pivot caliper brake?
Nearly all modern road bikes use dual pivot caliper brakes. They are simple, light and effective. Back in the dear, dead days of my youth, most road bikes (we called them 10-speeds) had either side pull or center pull brakes. Older single pivot, side pull brakes had an annoying habit of rotating around their mounting bolt. This would cause a brake pad to drag on the rim. Center pull brakes didn’t drag in this fashion, but required an extra bracket mounted on the bike to provide a platform against which the brake cable pulled the straddle wire which activated the brake calipers.

Cantilevers are lighter and simpler than center pull brakes but require the same type of bracket for the cable. Additionally, they require bosses on the fork and frame for the brakes to mount to. Well adjusted cantilevers work well, but otherwise, they are merely advisory. Many modern mountain bikes are outfitte
