Treks are unpopular in my opinion because the bought up Gary Fisher, Bontrager, klein and Greg Lemond bikes.
Because they were such a large corporation they could afford to buy out all of the smaller companies, and get rid of a lot of the competition in one fowl swoop. Now all the companies are shadows of what they were before the were bought out. Just my 2 pence worth
The bike snob in us all wants to ride a nice bike with some coolness attached, but the bulk of the market is bikes at a price, this is what Trek do very well. As for the buying of other companys the other option could have been the companys closed down, whats better Trek owned Fisher or they go the way of Fat Chance, Onza etc, as much as we admire Gary Fisher, Keith Bontrager etc for what they did at the end of the day they are business men who are there to make a profit, and at the end of the day if they can sell there comapany and semi-retire/retire who can blame them, I know I would.
I Dont get the knocking the big guys, for producing bikes for every one.
