I have a 2005 Trek 5000. Its a great bike and has taken me over many miles. I used it recently for a 200km Brevet. After 2005 the Trek 5000 was not made in the USA and is not OCLV carbon. I dont have an issue with this but if you are after a made in the USA bike beware that after 05 this model was produced in China or Taiwan (sorry not sure which).
