The Nanogram Ultra Light cage weighs only 19 grams, but is inherently less fragile than other light weight carbon cages by virtue of its unique design. Made from unidirectional carbon fiber, the Nanogram Ultra Light's simple, elegant design positions the water bottle stop at the top of the cage rather than near the mount where it is most vulnerable. The Speedplay Nanogram cage combines this design feature with the natural resiliency of carbon to absorb the repetitive impacts of rough roads and from riders banging closed the water bottle top. As a bonus, the Nanogram cage includes lightweight aluminum fasteners and a BPA-Free Nanogram logo water bottle.
- At 19 grams, the Speedplay Nanogram Ultra is intended solely for road bike use.
