I've just bought a second hand bike with 2003 Campag Centaur and everytime i get out of the saddle to sprint or do a big hill i get a pretty bad creaking sound from the cranks.
When i got the bike it was only 10 weeks old (4000km) and had just been serviced
I've tried tightening the crank bolts and that helped for one ride.
Then i tried pulling the bolts out and re greasing them, again that helped for a ride but now the sound is back.
I'm thinking that perhaps the cranks need to be pulled off and re installed.
Any ideas?
