MCS Brake Post Extender Description: The MCS Brake Post Extenders is a simple way to move your brake mounts if your brake pads aren't quite lining up with your rim. You might be putting a 1-1/8" or 1-3/8" wheel on a frame intended for a 1.75" or vice versa. With these brake post extenders, you can move your brakes either 16mm forward or backward depending on your application. Note: You will need to swap the sides that the extenders are on to change the orientation.
