This is a great tool, (I have a newer version that is wireless), and the magnet is strong that sticks to the end of the axle. But magnets do not offer much resistance to "sheer force", and this axle mounted unit can move pretty easily when taking the bike off the stand, (and you will not notice it unless you put the bike back on the stand to see if it still reads zero. If not, it slid). I found a easy cure to hold it in place. Use a thin piece of double sided sticky tape on the end of the axle before you stick the unit to it, (make sure you align it well before sticking them together). This will stop the unit from sliding a bit on the end of the axle and give you a very precise meaurement.
I love being able to set the sag myself. But after you "zero it out" with the tire off the ground (on the stand), be very careful how you remove the bike from the stand and set the wheel on the ground softly. The magnet of the unit on the axle can move, (I will make a pin for mine). If it moves, you won't know it until you put the bike back on the stand again, (be gentle here too), to see if it is still reading "zero". The first time I did it, it moved 2mm.
You said you check it often. But how often are you having to adjust it? Meaning how often does your sag change. And why does it change with you touching the spring preload adjuster.
I like to check it just to make sure nothing has changed. It doesn't change very often but it can happen and has happened to me. Any time you put less or more tension on your spring, you're going to change your sag numbers. I also like to experiment with sag numbers and sometimes I can't remember what my sag is at since my last ride haha. - Chase
@@rmatvmc Springs will sack out over time, but you should not have to check it often. If it changes several times in a year, (and you stay the same weight), the spring is probably made in china, out of cheese. I think you found more sag one day because you had to take a poop. A Pizza can stick with you for days. hehe
Rider sag on most full size bikes will be right around 100 mm but your bike's owner manual will have an exact window for your specific bike. We have a great video on setting sag that you can check out here: ua-cam.com/video/ZXCOoy9T0vc/v-deo.html
A good "rule of thumb" is 1/3rd of your total rear wheel travel. My YZ250 for example has 12.4" of travel at the rear wheel. That is 314.96mm. 314.96mm x .33 = 103.9mm, and just about exactly where most people set it.
I found a good spot to hook the end of the measuring cable inside of the number plate, so I did not have to drill a hole. The clamp is optional, that's all. Some people may not want to drill a hole or be able to find a good place to hook it up, so they can use the clamp. I like the choices.

Love your vids Chase
Thanks!

Really need this product for my wr450 Yamaha...

Does the scale take in the fact that the length of the bracket and isn't on the point marked
I had the same question. Manufacturer video shows it more precisely: ua-cam.com/video/sy-mym-SLdM/v-deo.html
How much rider sag is required for the trail?

Why the clamp?.....Just put the string hook in the hole...done. JS
