gauges to create 3-D models of your gearing.

The rising tide of products that combine physical objects with mobile apps has come to do-it-yourself bike maintenance.
OTTO DesignWorks, a startup based a few miles south of Portland in Wilsonville, says its first product will offer “perfect shifting in under five minutes” for people with Shimano and SRAM 9-, 10- and 11-speed gear cassettes.
As the video below shows, the company sells gauges that can be attached to a cassette and derailleur. Its free mobile app then uses a smartphone camera and photogrammatry — the mathematically intensive process of turning images into three-dimensional modeling — to diagnose the situation and walk someone through the tuning process.
