According to the product introduction video, the system "doesn't require any prior bicycle service experience," and one should be able to achieve "perfect shifting in under 5 minutes." The company touts the precision of the system as being accurate to within +/- 0.125 mm. Holy cow.
They also claim that it can "diagnose bent dropout hangers, worn cables, and poorly adjusted limit screws." I suppose it makes sense that the system can diagnose dropout hangers and limit screws, since both of those things would be picked up by checking the alignment of the gauges. How on earth it can detect worn cables is beyond me. Then again, why would anyone possibly need an app to tell them their cables are worn? Are they frayed? Kinked? Rusty? Those should be clear just from looking.
I wonder if the app can diagnose THIS:
|The OTTO website calls this phone screenshot "augmented reality." I'll say it's "augmented." somehow they got the drivetrain on the left side of the bike!|
|Apparently the phone's camera "reads" the dots on the alignment gauges, then uses some algorithms to determine what adjustments are necessary. Listen to the slightly robotic-sounding woman's voice explain, "Turn your barrel adjuster 4 clicks clockwise." (photo from OTTO)|
I will say that, at $39, (that's for the gauges - the app is apparently free, but useless without the gauges) the OTTO Tuning System is at least a relatively inexpensive tool. The company says the system is Shimano and SRAM 9-10-11 speed compatible -- but not Campagnolo. I find that partially odd, since I was under the impression that the cog spacing of 11-speed drivetrain systems was the same for all three companies (at least that's what Lennard Zinn says). I guess it doesn't matter, though, since none of my bikes goes to 11. In fact, most of my bikes still use friction shifting. It probably goes without saying, but the OTTO Tuning System is also incompatible with friction -- and mostly unnecessary in any case.
There are demonstration videos on the OTTO website, or you can see their product introduction video right here:
Useful tool? Or another example of smartphone addiction? I wouldn't mind hearing some thoughts.
