Reverse Coil Shock Travel/Sag Indicator, Black

Pros

Does what it's supposed to do. more or less... i suppose. it tells you how much travel you've used and that's good because it's hard to tell on coils unless you have this tool!

Cons

The bad part is that you kind of need to do some math if you want to find out the exact percentage of travel you've used. definitely not intuitive but i did reach out to the manufacturers customer support and they were responsive and helpful, you just need to use the product more to really understand what info you can extract out of it.
also it's important to note that the mount that attaches to the piggyback of your coil shock is 3D printed and will likely become brittle and crack overtime or will just crack from impact. not super robust. and one last thing is that they mention you can keep the indicator attached to the bike when riding but then in the manual it says don't do that. i'm just keeping it on and once it breaks then oh well. i'll run the product through its paces.

Other Thoughts

as an experienced bike mechanic, it's nearly impossible to make a "universal" fitting part for bikes, especially for shocks that have hundreds of differing parts based on the bike you're riding. the manufacturer makes it sound like this tool instantly fixes the coil sag issue that many of us face and it DOES technically but not in a direct way if you want to know how much travel youve used in number terms
