If you can’t see the spoke hole centers all the way around the rim, you can usually count them by counting the number of grooves between the spoke Bolt patterns are comparatively easy to figure out if the head stampings are still on the rim, and you have a good idea of the overall diameter of the rim.
The easiest way to determine the bolt pattern on a rim is by using a gauge. A rim gauge looks like a screwdriver or a piece of tape and has a very thin diameter. The first thing you need to do is find the diameter of the rim.
