What Our Gearhead(R) Experts Are Saying:"I put the PRO Side Cage on a small-frame gravel build where there was no room for a second standard cage, and it solved the problem cleanly. The directional base plate kept the bottle locked in even on rough doubletrack where I expected it to eject."On a small frame, on a mountain bike, or anywhere that a standard center-pull cage creates a clearance problem, the PRO Side Bottle Cage earns its spot on the build. The reversible design lets you orient the pull to whichever side your riding style, frame geometry, or personal preference calls for, so hydration is always within reach without an awkward reach across the bike. AL-5052 alloy construction keeps the cage rigid through the impacts and vibration that would flex a lesser cage into unreliable territory, and the directional base plate adds a secondary retention point that prevents bottles from working loose over rough terrain. It pairs particularly well with the PRO Performance bottle, though it holds standard bottles securely too.
