Measuring a Trek for size?

[OakLeaf]

If it says center-to-top rather than center-to-center, I'd do it the same way I just outlined, but start measuring from the top of where the top tube joins the head tube. Even in the old days, the measurement was based on the top tube, because different manufacturers allowed widely different amounts of tubing above that level to support the seatpost.

If you subscribe to Adventure Cyclist magazine, there's a great article towards the back of the current copy (I received it yesterday) that discusses and shows what to measure on a bike when sizing.

It's a great magazine, my favorite in fact. They'll send you a sample copy if you'd like.
