Review on 🚴 Optimize Your Ride with Otto Tuning System 10, 11 Speed Cassette by James Townsend

This product is conceptually great and I was excited to try it in the hope that it would provide accuracy and near perfect settings. Attaching the plastic clips was very easy as advertised, but went downhill quickly. The first negative surprise came when I had to pay to use the app, and I wasn't talking about the cheap one-time payment that started off on a negative note. I paid for a 7 day usage plan only to find that the instructions for moving the chain to the specified rings on the cassette were not clear at all. And after a few adjustments based on my interpretation of the instructions, I found myself in worse shape than when I started. I ended up giving up using this device and manually changing the settings to get back to where I started. So now I'm the owner of a totally useless tool that I wanted to resell on ebay, but I couldn't feel good about charging for this product. Before you spend money on this I would suggest watching a YouTube video on setting high/low limits and using trunk governor to optimize indexing - it's cheaper, easier and you won't waste your money.
