Sunlite Cantilever / V-Brake Boss Replacement Set – M10 x 1.25 – Black (Pair)

These Sunlite brake bosses are standard replacement mounts for frames or forks that use cantilever or V-brake systems. They thread directly into existing brake boss mounts and provide the pivot point for rim brake arms.

This is typically used when original bosses are damaged, corroded, or missing, or during a frame or fork refresh.
