The SP Connect Aero Mount Pro is designed for the rider who wants speed. The lightest smartphone mount on the market with only 5g carbon reinforced plastic on the market for all lightweight enthusiasts. Secures to the flat surface of the stem with strong 3M double-sided tape. Front and back asymmetric shape allows you to set your phone slightly on the front or back during installation. In addition, the rubber ring around the stem secures the mount. You can set your smartphone on the aero mount and use it alone or conjunction with a cycle computer (Wahoo or Garmin) mounted on the outfront mount. If you want to use a cycle computer alone, simply slide the included Wahoo or Garmin adapter into the aero mount and you're ready to go. You can choose the best choice for indoor training such as Zwift, or for those who use a smartphone for actual use, or for those who use a cycon. In addition, if you want to use both, you can install it at the same time by securing the sixon with a factory out-front mount. Furthermore, when you do not install anything, you can install the included aero cap for a smart look. Please use it after about 24 hours until it is stable.
