Shop tours are always fun to read about. Recently Moots published an article giving insight to their small parts creation. They create quite a bit of parts inside their Colorado facility.
Another great article that was published awhile back is a photo driven tour of Industry Nine Wheels based out of North Carolina. This tour has great information on how they make their products and tons of detailed photos.
If you’re looking to pick up a set of Industry Nine wheels for yourself. JensonUSA usually has some of the best prices around. 20% right now on full wheelsets.
