Universal Support Bolt

Bought 6. One broke upon installation which is annoying. Ended up just using it anyway with only 2 mounts on one side and it worked to hold a full nalgene for 72 miles on gravel roads. Loss of a star because I think they are not super durable, but I don't know what else I would've used so I'll have order more anyway. Might try a smaller size this time and see if that helps

Perfection.

These things are as close as you can get to perfect for biking. I've been using them to build out a bikepacking setup and they've allowed me to use whatever bags I want while also carrying plenty of water on the bike. I used these to put a couple bottle cages on my seat stays and it was a complete game changer. Do yourself a favor and pick up a couple, you'll find something to use them for.

So far so good.

I attached a Manything cage under my downtube using King Cage USBs and put 200(mostly off pavement) miles on the set up in about a week and a half. I've heard the USBs *can* fail in this set up but an easy way to mitigate that is to run the straps around the downtube so the USBs aren't taking the whole brunt of the weight, so that's what I did. For the majority of the miles I had a 1.5L Nalgene in the cage and am happy to report that the entire setup worked flawlessly. Pictured is the set up with a 1L Nalgene for reference.
