Your bottle is staying put with gorilla grip strength
Do note that you have to pull it straight out so if you don’t have a much room between the front of the cage and the head tube you will probably want to go for the standard style cage

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.

Sleek look, lightweight, easy to slide my bottle out but haven’t lost it once even in chunky technical terrain

Very nice bottles

I could not fit two bottles on my SC Highball carbon that I plan to tour on this summer, and figured some genius would have a workaround. Sure enough. Two large bottles now take up the triangle void I have no interest in having a bag made for. Thankyou. My daughter loved the sticker as well.

Great quality, no aluminum oxide on my bottles. Clean look without extra material it frills. Made in the USA is a big plus.

They seem great! Ultra light weight and sturdy.

This thing is great. Lets me shift my downtube bottle up high enough to carry a big thermos in a minithing cage on the seat tube.

Quality craftsmanship , perfect cosmetically , made in the USA !

Work great, made in Colorado how can you go wrong!

There is nothing better than rolling thru snow and taking a break now and then. What makes it better is blackberry brandy. What makes it even better is having a cage that will hold a flask of blackberry brandy. This cage is as good as it gets. Thanks for creating it!

You ever just wanted something? These cages have been a want for 15 years for me. I never had the bike or the financial situation to get them. But this year I did! Slapped these bad boys on my custom Caletti Ti frame. The cardboard boxes they came in was heavier than the pair! Love ‘em!

Looks great and holds a bottle really well

I mounted the Iris cages to my Botched Bikes dragonfly and they hold the bottles nice and secure while giving that classic clean look. Can’t go wrong with king cages.
