When installing these adaptors it’s worth having a think about physics, and the limitations of your frame when you are loading two bottles on one set of frame bolts. When using the double bottle cage adaptor, with two full bottles, you are doubling the load that your frame water bottle bosses may have been designed for. To balance the load on the frame bottle bosses, particularly on light carbon frames, we recommend you keep a balanced load in the bottles side to side.
The Bottle Cage Double Adaptor has a full manufacturer warranty covering any issues with manufacturing defects and workmanship. The warranty does not cover damage due to improper assembly or follow-up maintenance, or lack of skill, competence or experience of the user or assembler.

Enables me to run a full frame bag on all my bikes with having 2x1L water bottles. No interference while paddling. Would suggest everyone picks one up. Good bit of kit.

Great piece of kit, easy to install and promptly delivered by Commuter Cycles. Excellent method for carrying extra water when using a full framebag.

have this mounted on a dually with a full frame bag and another cage taped under the frame. Gives me 3 litres of storage capacity for bikepacking plus 5L storage in the frame. I would recommend, its very light, the bottles arent in the way of your legs and are easily accessible for drinking

My last one broke after a lot of serious riding with 2 x 1 litre bottles in and I got another one because I love it so much. I then emailed cyclewerks just to give them some feedback as I figured they’re the kind of legends who like that and they said they’ve changed the design and sent me a new one to replace the old one. I love these kinds of businesses!

Very solid. Surprising to me initially, but doesn’t get in the way of my knees at all. Used with Zefal side-entry cages, and a Wolf Tooth B-RAD extender to move the mounts up near the stem. Fits under and beside my frame bag perfectly, but be aware that the eyelets extend out the back of the adaptor maybe 7 or 8mm: I taped over them to avoid wear on my bag.

Yep this is the bit of gear you’ve always needed and never knew, beats trying to hang bottles off of your suspension forks, allows you to run a frame bag and bottles plus puts them in a great position to grab when needed.
