It's probably a 1 1/8 inch.

But why don't you measure? It's not even necessary to remove the stem - just disassemble the stem cap (I assume you have an Ahead-system) and measure the inner diameter of the stem.

P. S.: 1 inch = 2,54 cm.

I bet it 1 1/8 steer tube. Not too many people requested 1 inch. I don't remember trek having 1 inch headtube forks. If it's a quill stem it's 1 inch. If its an ahead stem (Same as today's mtb stems) it's 1 1/8 diameter.

Hopes this help. The judy's blew alot of cartlegdes back then. Mag 21 where better, but where air with 2 inches of travel.
