Today’s QT is another homegrown one, from Tech Editor Jim Langley. It’s probably safe to say that if Jim didn’t know this, not many people do. Here’s what he wrote:
Thanks to the Professional Bicycle Mechanics Association I recently learned that all these years I’ve been using the wrong screwdriver to turn the limit screws on Japanese derailleurs!
It turns out that there is a Japanese screw standard (who knew?).
It looks a lot like a Phillips screw; however, you may have noticed when adjusting your Shimano derailleurs that the fit of a Phillips driver is a little loose and can slip.
What’s needed is a JIS screwdriver, which fits perfectly. Here’s a link to the one I bought and am now using: http://amzn.to/2v4IVeW
