Cool bike and I hope you kept that white Concor around!
It’s in the thread title. It is making me look through the whole thread. All I can see is he likes the bike, which he thinks is “whippy,” maybe whippy means it planes? I have a 1984 Trek 610 in smaller size (21”) and I have not felt the frame to be whippy. Perhaps it planes, a least with supple tires like Strada Bianca. The St and TT are standard 531 double butted profiles. The DT is identified as 10/7/10, which is the same DT as in the 531 db Super Tourist tube set.
The main tube specs are the same for the 610s, 620s, and 720s, and nearly all of the Reynolds bikes through their early and classic eras. Not my definition of flexy tubes.
