I just put my $ down for the Trek 7.5 FX Disc. It was raining so I only got a test ride on the trainer on a 7.6. The bike is very comfortable and the 17.5 fit like it was made for me. It felt more like a flat bar road bike than a mountain bike. I pick it up on Wednesday. I have Thursday to try it out and ride it some before I am housebound for my oncall shift. I'll provide a ride report after I have some time on it.
I'm super excited!
