Trek 520 Disc question
Does anyone know what model year of the 520 was the first to offer disc brakes, and the last year the 520 had a flat top tube? I'm wondering if there was any overlap between the 2, or in other words a model year when the Trek 520 was available with disc brakes but still had the flat top tube.

It's not a huge deal, I was just curious.
