Perfect bottle cage adapters, allowing the mounting of Anything Cages to suspension forks, or to mount a bottle cage on frames without bosses.  

They can be used to adapt a bottle mount to the down or seat tube of a great number of bikes.  Plain and simple, they work, and can be used in so many ways to adapt tools, cages etc.  

These are sold individually, and will work for most normal cages that you mount with standard M5 bolts.

Use 3 for the Many Things cage (other Cargo Cages are available), 2 for most regular bottle cages, 1 for something creative

Note.... Ron Andrews advises using electrical tape or cloth rim tape to protect your frame or fork legs. Not rubber inner tubes which he says can lead to clamp failure.

Another note... They don't work with the Salsa EXP Cage, the nylon body on that cage is too thick.

Four sizes... 
1 1/8" (28mm) for things like steel forks
1 3/8" (35mm) for things like steel frames and forks
1 5/8" (41mm) for things like suspension forks lowers
2" (50mm) for things like aluminium tube bikes

Sizing is for the maximum diameter so if in doubt size up.

“The USB is a versatile solution to a long-time conundrum. I am especially impressed by the build quality and the fact that it’s stainless steel. For whatever reason most of the new ‘adventure’ bikes fall short on having a down tube bottle mount, not to mention there’s no such thing as a suspension fork bottle mount. So the USB is a well thought out and timely little gadget. They seem solid but we’ll see how they hold up over the long haul, and I’ll make sure to update this after a few hundred miles.” – Logan
