I got this at Tahoe bike shop in 1988. Bought just the frame, and built it up. Was working at Decision Bicycle in Gardnerville NV. Have a ton of miles on it with the Alta Alpine bike club. Raced juniors against Lance Armstrong on it. Never saw him. They moved him up to pro men the next day. Comfy bike. Let's see your TSDI, and story behind it. Have a good one everybody!
