Aero and Tube Specific Water Bottle Cages 
Not only are these new Factor/BLK Inc cages aero, but they are tube-specific. Unlike other aero cages, they do not require a specific bottle or an attachment.

The BLK Inc OSTRO downtube cage bridges the gap between the downtube and the water bottle. It promotes longer flow attachment and reduces localized drag — plus, it holds a water bottle!

The Factor design team chose a different aerodynamic approach for the Sprint Cage. It acts as a high-speed flow management device. It’s most aerodynamically functional when a rider ejects their bottle before the final sprint. The foil profiles and precise spacing with the seat tube funnel air tightly across the tube and transition it to the rear wheel. Making you faster for the times when it’s absolutely needed — like a tour stage or a town line sprint.
