They have a nice line of hybrids w/front suspensions - the Katai, Utopia, and Montare. As soon as the weather and time availability align, I will be test riding the Katai - the entry level one of the bunch. The owner of my LBS has the Montare, along with a dual suspension mtb and a dedicated road bike. He told me that if he had to choose only one, he'd keep the Montare. All 3 of them have disc brakes, & you could theoretically keep two wheelsets available for different conditions/applications.
On a broader note, although Trek owns GF (and Lemond, I think), another LBS owner told me that Trek keeps the manufacturing and design processes somewhat separate.
