My bike’s profile in the app.
One of the cool things about having a good friend or a partner with a different knowledge set than you is that it gives you access to expertise without having to be an expert in everything yourself. Since my partner is a bike mechanic, it means I don’t have to master a headset press — and he doesn’t have to master WordPress.
Although I’m very familiar with basic bike maintenance, I’m by no means an expert. Sure, I understand how to adjust my derailleur, but I’m always going on guesswork. And un-expert guesswork, at that.
That’s the problem that the new derailleur tuning system from OTTO DesignWorks, a startup based a few miles south of Portland in Wilsonville, is trying to solve. Their OTTO Tuning System uses an iPhone’s camera, visual alignment technology, and a set of gauges to help you quickly adjust your derailleur. It’s compatible with most Shimano and SRAM 9-, 10- and 11-speed cassettes, and costs $39.
