自行车变速器调整图解原理（有了这套自行车变速器自动校正系统）

懒的看文字的话，您可以点击这里，查看这套神奇系统的完整视频。

If you find gear adjustment on a par with witchcraft andnuclear physics, OTTO’s Tuning System could be for you. At the time of writing,it’s compatible with most shimano and sram 9-11-speed drivetrains. It won’twork with campagnolo, Android phones or clutch rear derailleurs on currentsingle ring systems.

如果你对自行车变速的调整一无所知，每次调整都好像在拆炸弹，那么这样一套otto的后拨自动校正系统绝对是你的首选，让你化身大神级人物。这套系统可以和shimano和sram的9-11后拨完美契合。但是还暂时不支持campagnolo系统。并且app还暂时只有ios系统版本。

The apparent phone-brand prejudice – it only works withiPhone5 or6 – is down to the front-facing camera the app uses to ‘see’ the gauge targets.The process relies on consistency and accurate calibration, so it’s essentialto use the same hardware, and these iPhones share the same front cameras.Android phones are developed by different companies, and their cameras allvary, as do the iPhone’s more powerful rear cameras. Theoretically it ispossible to support every phone camera, but the costs involved are prohibitive,and for now, this situation is unlikely to change.

这套系统对手机的支持也不是特别的好，目前只支持苹果手机，并且只能用前置摄像头来搜寻测量目标。这个原因是因为苹果手机有一只的摄像头设置，和大多数安卓手机比起来，硬件上的一致性，可以保证系统的精确校准。目前公司正在设计尽可能支持更多手机的app更新，虽然这样的成本是很高的。

Using the system also requires good lighting – sufficient tocomfortably read a book – so allowing the Photogrammetry function to read thetargets in much the same way as face-recognition software does in moderncameras.

另外，使用这套系统需要一个良好的照明环境，软件测量的目标的方式和现在的人脸识别方式基本相同。

The plastic gauges have 12 rear-facing targets, whosepositions are scanned at the factory, and stored within the unique QR code oneach box. The free phone app reads the code, and calibrates your camera andgauges to measure 3D positional differences between the rear derailleur andcassette of less than 1000th of an inch.

塑料量规有12个向后的定位侦测点，其位置是在工厂以前经过扫描，并且数据已经被存贮在了每一个盒子上唯一的二维码中。你可以用手机app扫描二维码，并且校准你的相机和量规，他可以测量后拨链器和链条之间位置的细微差异。

After creating profiles within the app for each bike youintend to adjust, you’re ready to start. Slip the orange gauge over the upperjockeywheel,and the blue one between the frame and cassette, then align both sets oftargets as near to parallel as possible.

首先，你要先设置你的自行车的基本档案，然后就可以开始了。先将橙色量规安装到你的后拨导轮上，然后把蓝色量规安装到位，之后让两个量规上的侦测目标点尽量对齐。

Your options are to Check or Tune rear derailleur alignment.Checking is free and takes under a minute, whereas a complete Tune incurs anin-app cost per quarter (90 days £7.99/$11.99) or year (£19.99/$26.99), tocover current and future development.

你所需要做的就是然后拨链器对齐。检查是免费的，仅需要一分钟的时间，但是完整的调整过程，需要每个季度11.99美元，或者每年26.99美元的花费。

A Check results in an accuracy index score plus correctivebarrel adjuster tweaks, and can tell if your derailleur or hanger are bent. Thetarget score is within 0.125mm of perfect, and as 11-speed chains are only0.4mm from the next sprocket, setup needs to be precise.

检查结果的精准分数加上校正和调整以后，系统可以告诉你你的变速器或者尾勾是否弯曲。目标得分如果在0.125以内，而11速链条距离下一个齿轮片的距离只有0.4mm，所以设置需要更加精准。

Tuning can be Fast, using only the barrel adjuster, orComplete, where you’ll reset cable tension and mech limit screws. Di2 and eTapsystems can be checked, but not tuned.

调节器可以快速的，通过系统计算，给出你重新设计变速线松紧或者限位螺丝调整等的方案给你进行变速器的调整。Di2和eTap系统目前还只能监测，无法给出调整方案。

We found the system foolproof, with consistent results whenfollowing the instructions. For most riders, using the free Check function, andadjusting as necessary will be sufficient, unless you’re starting from scratchand need walking through every setup stage.

我们发现系统的测试非常准确，按照说明进行操作的话结果是非常一致的。对于大多数车手来说，使用免费的监测功能斌个根据需要进行调整就已经足够了，除非你需要从头开始，并且需要在每个阶段都需要进行帮助。

It’s light and portable, so easy to pack for travel, whenderailleur alignment could be affected, and offers peace of mind for the lesstechnically-savvy. It does have quite narrow appeal given that it’s notuniversally compatible with drivetrains and phones alike, but is innovative andjust a little magical.

这套系统轻巧便携，可以帮助你设置的后变速器。但是他的兼容性不是很大，因为不能普遍使用在所有手机上。，但是他很具有创新性，而且非常神奇不是吗？
