My limited experience with Trek and Bontrager (which are the same) is:

They are not great products -- but they are well backed by the manufacturer. So, any failure (in a reasonable amount of time) will be replaced with, well, more of the same. But, when I buy something at my LBS (which is GREAT!), he usually pushes Bontrager on me -- not because he is overly impressed with the stuff -- but because he knows it will be covered under warrenty if/when it breaks...
