Box Two Brake Post Extender

The Box Two Brake Post Extenders are a great option for riders who have changed from one sized wheel to another and would like to keep the same frame, for example, riding a Pro XL frame and changing from a 20x1.5 to 20x1 3/8 sized wheel. These mounts move the brake calipers 16mm so that the arms allow the brake pads to be run in correspondence to the rim.
