i finished putting my new bike together with sugino 75 BB and cranks, it creaks when i put pressure onto the drive train. i have removed everything (cranks, chain, bb), wipe down and regrease and retorque. still creaks. could it be the frame? sugion 75 bb and cranks are quiet on my 722ts. i took my seatpost and saddle off the 722ts for a test ride, now i hear creaking from the saddle also. whats going on?!
