Mandible Water Bottle Cage

3 out of 5 stars

Mandible Water Bottle Cage

The Arundel Mandible Water Bottle Cage holds your bottle with two slender arms that create a smaller cross section yet provide up to 40% more bottle-grabbing power than other cages. The Mandible is a design perfectionist's dream: more strength in a smaller package. Arundel offers their minimalist cage with minimalist graphics: No colored decals here.

You can use the Mandible for road, mountain, cross, or triathlon. Arundel knew that their new Mandible cage couldn't be just another fanciful design with a new logo and a crazy name created for the sole purpose of adding another item in their catalog. The Mandible had to work, and work better than anything else available. Not only does the cage design increase holding power, Arundel lightened the structure by adding a foam core to the carbon cage. Most cages simply cut out the center to save weight. Typically, this process exposes the mounting bolts and arm edges and makes it hard to slip a bottle in or out. The Mandible's smooth, three dimensional form leaves nothing for the bottom of a bottle to catch on when you pull it out.


  • High-grip, low-mass bottle cage to keep water close
  • Carbon fiber construction with foam core for minimized weight
  • Sleek design prevents catches when pulling bottle out

Necessary? Nope. Awesome? Yep!

I've put it through the wringer

I've been crushing new Tour de Commute PRs since buying two of these. The (psychological) gains of dope cages (that no one else sees) is significant. In my testing, the Matte is 4.7% more efficient than the Oil Slick variations. This is likely caused by them not properly complimenting my Canyon frame, therefore reducing said psych gains. Alright- with the caveat that my previous Mandibles set were stolen, along with my bike, these have stood years of use and my new set looks exactly the same. Are they *really* necessary for any of us? Def not. Do they work? Sometimes a little too well but then, when bombing down the ridiculously pot-riddled tarmac that are Seattle streets or single track in the foothills, my bottles don't rattle like my teeth and I know they aren't going to fly off.
