I second Mark's comments about Tim. Trek spent a lot of money on this steel lug frame production process. Just shortly after it was perfected the glued alloy frame made it mostly useless. Tim tried to make steel lugged frames in the Seattle (in 2000 or so) area using all state of the art frame building machines. He made the last lugged Paramount frames there. For various reasons the company did not make it. 70 deg. today here, I got a ride in.
