KandyBikes dual water bottle cage adapter
This simple 3D printed adapter changes any water bottle cage mount into a double. The angle is set so that with two standard steel water bottle cages mounted, 2 water bottles will fit in between the crank arms on a standard 168 q factor MTB crankset. This item will work anywhere a cage mount in available. If one would like to also pruchase a King cage top cap mount, 2 water bottles can be easily and securely mounted on the top cap. This is a convenient and safe placement for XC racers. It is also a strong extra option for bike packers.
