creaking noise

[steveoo]

Since the first service was done two weeks ago my bike has developed a creaking noise.seems to happen when i depress the left pedal.
Anyone have any ideas?

It could be so many different things, but the most obvious things to check are whether the crank arms properly tightened,or even teh pedals. It may be a loose or worn bottom bracket, or knackered pedal axle/bearing.

Could be most almsot anything transmiting the creak althoughmy 1st check would be the tightness of the cranks arms , i had the same and it was bacuse the left hand crank was not tight enough.
Today i have hopefully solved an annoying creak as i found the chain ring bolts were not fully tightened.....

Agree it could be almost anything but on my bike a creak with each pedal rotation is usually a dirty seat post which needs a good clean, a pedal cleat which needs a drop of oil or a dab of grease required where the cable outers sit in the guides at the top of the down tube.

Weird huh? It really can be anything and will take a methodical approach to rule everything out.
