At first I thought it was just me getting out old. Then it got squirrelly. Descending, I had to stop pedaling at 35 mph just to keep it in a reasonably straight line. If there was a crosswind, my knees were clamped to the top tube. I had to borrow bikes from the shop's rental fleet to lead the Saturday group ride. I couldn't trust myself riding next to anyone. I retired the bike when I noticed that the wheelbase got longer when I sat on it.
YIKES! I was going to say "flexy", but this goes well beyond flexy. Sounds like a crack in the frame somewhere.
