This video takes you on a tour of Trek’s Waterloo, Wisconsin factory, where they still make many of their top-end bikes like the Madone 6 and 7, and includes their custom paint and bike builder facility Project One.

Trek Bicycles, founded in 1976, actually started making their first carbon fibre bicycles frames with the introduction of the 5500 and 5200 road bikes in 1992. They used Trek’s proprietary OCLV (Optimum Compaction, Low Void) manufacturing process, which they still use to this day.  While many of the cheaper carbon bikes are now made in Taiwan, they still make their top of the range models in the US.

And if you order a bike through Trek's Project One website, this is where they are assembled. The custom bike builder lets you choose from a raft of paint options as well as specifying the wheels, groupset and components.
