Trek 7000 Steerer Diameter

We probably need to know how old it is first. The "7000" moniker used to be applied to a mountain bike model and is more recently applied to a hybrid model. In both cases they use quill stems. I would assume the older one is a 1" and the latter a 1.125" but i can't be sure. Measuring the quill diameter (just above where it sticks out of the top of the headset) will help.
