I got this just because I didn't trust my eye-ball alignment after replacing the chain. Simple enough to use, and made me feel more comfortable that the alignment was good. I had to take the chain guard off so I could get a good sight line.
All Motion Pro tools are high quality and do the job they were designed for very well. This chain alignment tool is no exception. Easy to use and gives you peace of mind knowing the alignment is exact.
So easy to use and a must to properly align your rear tire/sprocket if you don't have clicking version. Since I now do my own tires, this will take all the guess work out of my alignment. Plus it is inexpensive, so a No Brainer :)
Never again rely on inaccurate stamped swing arm chain adjustment markings again. This easily mounts on your sprocket with one screw and serves as a visual aid to properly align your chain. No more guess work.
