For any of you who may be cyclists or manufacturing fans, here is a fun post from Guy Kawasaki: a visit to the Trek bicycle R&D and frame manufacturing facility in Waterloo, Wisconsin.
Maybe not the leanest shop I’ve ever seen, but there is not a ton of inventory in those pictures. There are hints of build-to-order, at least in the paint line (“Project One”). This facility makes frames which are assembled elsewhere, and there are some shots of finished goods. If they fill that truck up in a day, we see maybe just a few hours worth of FGI.
