If you're looking for a lightweight carbon fibre water bottle cage to complement the beauty of today's exotic bicycles then look no further than Speedplay's Nanogram Water Bottle Cage. It is inherently less fragile than other lightweight carbon cages by virtue of its unique design. Made from unidirectional carbon fibre the Nanograms 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 aluminium fasteners and a BPA-Free Nanogram logo water bottle.
