At road.cc every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.What the road.cc scores mean
Good scores are more common than bad, because fortunately good products are more common than bad.
The Apidura Bottle Cage Adapter gives you the option of carrying a large bottle on a small or bag-cluttered frame, by letting you adjust where the cage sits. It's a neat solution that is well made and works with both two- and three-bolt cages.
This adapter gives up to 55mm of adjustment, which is more than most similar designs. It achieves this by way of the two long slots, and using two of the three bolts on the adapter you then fix your bottle cage to the adapter – or use all three to fit three-bolt cargo cage mounts.
It's a smart solution, and allowed me to fit a 750ml bottle to my gravel bike even with the main triangle sporting a large frame bag.
Made from 6061-T6 aluminium alloy it's strong, and loaded bottles won't flex it. The anodised finish will keep it looking as good as new for a very long time, too.
In fact, the quality is top notch in general, with all edges either chamfered or rounded to remove any sharp corners and stainless-steel hex bolts included.
At £21 it's not the cheapest option. The Topeak Alt-Position Cage Mounts are £13.99, for instance, and that's for a pair. They only move things to another fixed position though, and the only adjustment is by rotating the bracket, so you don't get as much versatility.
The BBB AdaptRail has a similar design to the Apidura, is available £18.99 and comes in three sizes. I think the Apidura has a higher quality look, though.
This is a well-made, easy to use and strong piece of kit that gives plenty of versatility regardless of your frame size.
Simple and well executed design for making space on heavily-loaded or small frames

Size tested: n/a
Tell us what the product is for and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?
Apidura says, "Create more space for bottles alongside a frame pack and convert two-bolt bottle cage mounts into three-bolt cargo cage mounts. The Innovation Lab Bottle Cage Adapter makes it possible to lower or raise bottle cages by 55mm and converts standard two-bolt mounts into three-bolt mounts, allowing for larger cages and greater carrying capacity.
"The bottle cage relocator simply bolts onto bottle cage mounts, creating 55mm of vertical movement to make it easier to fit bottles alongside a frame pack. Using the supplied bolts, the bottle cage is then attached directly to the bottle cage adjuster. With three mounting points available, it is possible to convert standard two-bolt mounts into three-bolt mounts, capable of carrying cargo cages and increasing carrying capacity."
It is a well made piece of kit that brings extra versatility to your road or gravel frame.
