I have a mid 80's raliegh technium Trilite Scott Tinley model. I recently had it rebuilt and tuned and working great. The last two rides (about 120 miles since the tune up) the bike is creaking more and more. When I got home I tugged around on the parts and it seems to be the seat post? If it is tight enough to keep the seat in place, can it be loose enough to creak? I know these frames have a bad rep for cracking, but I don't see any signs of it. Could it be my cranks as well?
Everything is riding and shifting fine, but I'm not sneaking up on anyone. Any ideas?
I am 6'4 and 230 pnds if that helps troubleshoot.
