Standard Bike Rack Lowering Adapter Kit

Some bike racks position to accessory port far enough under the bike rack as to make it impossible to attach rotating attachment devices.  This kit will lower the mounting position of a standard bike rack accessory by 25 mm (1 in) to resolve this problem and allow Garmin Varia, Magene, Bryton, and other similar devices to be attached. This kit includes all necessary hardware and is made from high-strength carbon fiber composite material.
