Be it that you use a bicycle as transport, as a hobby, or as a sport, it is a necessity to have your bicycle tuned properly and functioning seamlessly. If you’ve been struggling with the gears and they just seem to never set right, then you’re definitely going to need the OTTO Bicycle Tuning System.
The Otto is an extremely easy to use rear derailleur tuner that allows you to fine tune your bicycle’s gears and derailleur for seamless functioning.
The Otto uses a combination of mechanical and technological devices to give you a precise tuning that you won’t be able to achieve in any other way. The best part is that it’s extremely easy to use and can be used by anyone that has very little mechanical knowledge when it comes to the world of cycling. Check out the instructional video below.
The Otto works in conjunction with a smartphone application and to use it, you simply place the Otto on your drive train and then align it with your phone’s camera. It will then analyze the results and give you an index score which will tell you exactly how much your drivetrain and derailleur needs to be adjusted and to which side. The Otto will also give you angle and twist measurements that will inform you if your derailleur or drive train are bent and need replacing.
The accuracy of the Otto is also uncanny since it has an accuracy of 0.005” (0.125mm) and is compatible with Shimano or SRAM 9, 10 and 11 speed drivetrains. However, the Otto app is only compatible with iPhone 5 and upwards running iOS 7 and iOS 8.
