Overall Review:

The Park Tool ruler is the tool that someone that truly has everything else might think is a necessary purchase to round out their tool collection. That is what I thought at least when I saw it hanging up in the shop where I worked at first. If you are a person that works on wheels fairly often, or older bikes that may have odd bearing sizes, this is actually a useful tool. Fixing up old or odd bikes, I used the tool numerous times to double check bearing size and you can do so much faster and easier than using a set of calipers. I also used the tool to double check spoke length and the hole that you hook spokes onto ensures that you get the right length quickly and accurately. I found this especially useful when digging through a box of unlabeled spokes of multiple sizes. Also, although this is obvious, it functions as a normal ruler which can be handy at times. The Park Tool blue also matches your other shiny tools, so you look way more pro than your buddy with a silver ruler… so that is a bonus.
