The Specialized S-Works Rib Cage II Carbon Top Load Water Bottle Cage Pair delivers a clean blend of lightweight design and reliable retention, tipping the scales at just 38g for the pair. Built from high-modulus carbon fiber, it’s stiff where it counts, keeping bottles locked in through fast descents and rough terrain. The aerodynamic profile is subtle but intentional, and the top-load access suits tight geometries or aero frames. With a secure fit and sleek look, this pair is made for riders who want function without flash—just dependable performance every time you reach for a drink.
