Description
Quickly check for damaged links on 11 and 12 speed chains. Place the tool over the chain and run the chain through, any damaged link will catch. Much faster and more accurate than a visual check. You'll notice that it does catch on the quick link in the video, but not too much, and it's easy to confirm that it is in fact the quick link that catches.
Printed in black and grey to quickly tell the 11 speed (grey) side from the 12 speed (black) side. Other colors are possible but would also likely wind up looking pretty bad after only a couple chains. Still, let me know if you'd prefer a different color.
Now also available in a 9 and 10 speed version for checking older drivetrains. 8 speed version to come in a future all-in-one design.
Thanks to Todd of Cowbell Bike Shop for the idea, based on a tool once made by Sachs to do the same thing for 8 speed chains. Also thanks to John Majors for requesting the 9/10 speed version.
Also et me know if you would be interested in a version for other chain widths.
