The Wolf Tooth B-RAD Base is perfect for moving your bottle cages to create more room for a frame bag. It's usually most useful on the seat tube cage, which is often placed in a higher-than-optimal spot for a Partial Frame Bag.

The B-RAD Base is also useful for some Wedge Frame Bags, in order to fit a larger bottle behind the frame bag - such as our massive 36oz AZ Panda Bottle.
