Side Bottle Cage

What Our Gearhead® Experts Are Saying:

"This comes up on builds where the frame geometry simply does not allow two standard cages without bottle and knee clearance issues. The reversible base plate is the key detail, it lets me orient the pull to match the rider's dominant hand and riding style, and the AL-5052 alloy is rigid enough that there is no flex-induced bottle ejection even on aggressive terrain."

Hydration access on a moving bike is a function of cage placement, pull direction, and retention security. When any one of those three factors is compromised, the rider either skips hydration or risks a fumble mid-ride. The PRO Side Bottle Cage addresses all three with a design built specifically for the scenarios where a standard forward-pull cage is not a viable option.

The AL-5052 alloy construction provides the structural rigidity that side-pull cages require to hold a bottle securely under lateral load. A standard cage relies on the natural downward force of gravity and straight-line pull to retain the bottle. A side-pull cage must hold the bottle against a lateral extraction vector while simultaneously resisting the vibration and impacts of off-road terrain or road chatter. The AL-5052 alloy resists the flex that would otherwise widen the cage opening under repeated stress, while the directional base plate adds a physical retention barrier at the bottle base that prevents downward ejection on rough surfaces.

The reversible mounting design is the primary fit consideration. The cage attaches to a directional base plate that can be oriented to accept extraction from either the left or right side, a detail that matters when working around frame geometry, knee clearance, or cable routing on small-frame road bikes, gravel builds, and mountain bikes where two standard cages are not geometrically possible. Optimized for use with the PRO Performance bottle, the cage also accepts standard bottles with reliable retention. For any build where clearance is the constraint and hydration access cannot be compromised, the PRO Side Bottle Cage is the correct specification.
