TorHans Aero 20 Hydration System The wind tunnel proven, fastest system to carry fluids while staying tucked in the aero position. Just like the Aero 30™, the Aero 20™ is a high aspect ratio, airfoil design from bottom to top of the Aero mast. Elliptical leading edge keeps this bottle fast whether it is mounted horizontally or tilted towards you if using S-bend aero extensions. This bottle has two channels to mount the high or low depending on rider preference. The TorHans AeroTray™ can be inserted onto the unused channel. New dual barrier XFlow™ cover makes it easy to refill on the fly without the contents splashing out. This bottle also comes with the ‘no cut’ cover to use during training or shorter Triathlon or Time Trial events. And of course comes with the drag saving Aero mast and straw. Just like all TorHans™ products the Aero 20™ is BPA free. Works with the TorHans™ Aero Mount™ and Aero Tray™ (sold separately) Includes: 22oz Aero bottle (650ml) AeroFlow™ straw housing & straw XFlow™ fill-on-the-go cap Aero bar dual-channel mounting system - the channels are molded in the bottle. The aero mount is sold separately.
