Otto Design Works says that you can let your phone do the tuning with their “vision app” and hardware kit. As far fetched as this sounds, should we really be surprised? We use our phones for far more things than we imagined just 5 years ago and who knows, 5 years from now we might be performing our own root canals with the latest iPhone 12.

I want to begin by saying, nothing can beat an experienced mechanic. There can be a number of things affecting your shifting and it is never in our best interest to take a chance with something we’re about to take on a long journey…. that can easily ruin said journey. However, a mechanic may not always be available. Out camping or even on a ride, if you are not quite sure how all those cables and gear thingys work, this actually could be a valuable “tool”.
The Otto Tuning System app uses your iPhone’s camera (Android will be available in 2016), and pairs with a hardware kit which includes two “Vision Gauges”. Using “photogrammetry“, developed by scientists and computer engineers, the app has both a check and tune functionality that can determine if things are in the right place within 0.001 inches. The system determines where the recorded shift positions are and finds the component location. Algorithms use this information to calculate the ideal settings which are communicated to the user through the OTTO software. It will then either confirm the bicycle component has been adjusted to its ideal location, or it will provide the user with instructions on how to adjust it.
There are 2 levels of adjustment you can choose from. “Check” allows you to confirm the accuracy of your bike’s shifting and whether or not additional adjustments are needed. “Tune” gives you the option of a simple barrel adjustment (i.e. cable tension), or a complete tune, which includes adjusting the high & low limit screws, and cable tension. It can even determine if you have a bent derailleur hanger. The Otto Tune System can be set up with multiple bike profiles within the app to easily work between various bikes. It currently only works with Shimano/SRAM 9, 10 & 11 speed systems but a Campagnolo system is due in 2016.
