The Arundel Mandible sits at the top of their bottle cage lineup for a reason. While the Dave-O established what a modern carbon cage should look like, the Mandible refines that design with one clear goal: bottles stay put no matter what you ride through. The geometrically-shaped arms use thicker cross sections than the Dave-O, which translates to a substantially stiffer grip on bottles without making them difficult to extract. That tighter hold matters when you're rattling down gravel descents or hitting rough pavement at speed.

Arundel achieves that security through foam core construction inside the carbon arms. Most cages just hollow out the center to drop weight, which often leaves sharp edges or weak points. The foam core lets Arundel build thicker, stronger arms while keeping weight at 28 grams per cage. The result is a cage that can survive real abuse. These have weathered Grand Tours, Spring Classics, World Championships, and everything else professional racing throws at equipment. If you've lost a bottle to rough roads before, the Mandible addresses that frustration directly.

The cage's shape makes bottle insertion smooth even when you're not looking. Flared edges at the top guide bottles into position, and the arms flex just enough to accept the bottle before gripping it securely. There are no sharp edges to snag when you're pulling a bottle out mid-ride. The three-dimensional form keeps the mounting bolt heads recessed and the arm edges rounded, so everything feels smooth whether you're inserting or removing bottles. Two sets of mounting holes give you 20 millimeters of vertical adjustment, which helps with frame clearance or lets you position the cage lower for larger bottles.... Read More
