Origin 8 Brake Boss Plugs

The Origin Brake Boss Plugs at J&R Bicycles may be a small component but it has a big impact on the longevity of your frame once you have converted brakes. These plugs fit into the holes left behind when you convert a cantilever or liner-pull brake setup over to disc brakes. Not only does this allow for a nice clean look, but they protect the inside of the frame from excessive wear and damage.
