Speedplay’s Nanogram carbon fiber bottle cages comes in two versions: the 19-gram Nanogram Ultra Light cage is intended for road bike use only, while the Nanogram cage, at 27 grams, gets the go-ahead for offroad use or behind the saddle triathlon use.

The company says the cages are stronger than other superlight cages in part because the bottle stop is at the top of the bottle, not the bottom. The cages come complete with alloy bolts and a bottle.
