Okay, as many of you know, I receive a lot of stuff to review, and I will have you know that when I opened the product, I had no idea what it is. Seriously, I get a lot of stuff to review, and sometimes I just forget who even sends it to me. I’ll be honest and say that unless you know what this is, these products are a big question mark.

Fortunately, as a writer, I feel a need to do research. This is the Tuning System 2.0, and it is the first voice-guided iPhone vision tool and application that can check the adjustments in under 60 seconds.

As you might have guessed, this is made for serious cyclists, and it provides a “thorough assessment of your shifting and derailleur angles in approximately 30 seconds”. All you got to use the iPHones’ camera as well as a set of engineered gauges to check the shifting alignment, and even has verbal prompts to lead the users through any needed adjustments.

Yes, this is an application that is free, and has levels of functionality of “Check” and “Tune”, with a multi bike profile feature. The end result is a better and smoother ride.

If this is something that you, as a biker, that you can get behind, head on over to the Otto Designworks site and lay down $39.00 for it. You can get the 10 and 11 speed cassette or the 9 speed cassette.
