I want to fit this bottle holder on my bike but the attachment seems too thin for the frame tubes. I believe this is a universal bottle holder and my bike isn’t of unusual size or tube girth. Am I missing something here or this just won’t fit?

P. S. Unlike my mountain bike, this bike (Claud Butler Legend) does not have pre-drilled holes for accessories on the frame.

    There is no "standard" size for bike frame tubing anymore. Virtually all modern frames have larger tubes than the old classic steel frames. Commented Aug 1, 2018 at 12:05

    That adapter is meant for either the seat tube or other such thinner tubes on bikes which do not have bottle cage bolts. If yours has a quil stem or a think handle bar, or similar, you can try them too. Seat tube might be best bet

That does not appear to be a attachment for mounting a bottle cage to a frame tube. The two holes in the mount appear to match the two holes in the upper plate of the cage, which orients the mount incorrectly for clamping a frame tube. My guess is that it's for mounting to handlebars - which have a standard diameter, unlike frame tubes.

mounts for frame tubes do exist. They typically use two adjustable straps of some kind to accommodate different size frame tubes. You want something with a beefy strap that can be tightened sufficiently to stop the cage rotating on the frame tube.

  • But bottle holder on handle bars? Does anyone even do that?

  • Casual riders on upright bikes who don't want to reach down into the frame typically. Commented Aug 1, 2018 at 11:16
  • @Neeku - some Eroica riders put their bottles on the steering bar to comply with the respective era looks.

  • Some women’s frames don’t have room for a bottle cage

  • If I hadn't been using a bar bag I'd have used that mount on my tourer for a camping trip. Instead I fitted bottle holders to the forks. Bottles on bars also works for full suspension mountain bikes (though if you really need full sus you might not want a bottle there).
