Creaking from the drive train

It's the saddle rails. The noise always seems to come from the BB area.

Come back on here and tell us we're right.

I am placing my bet on the pedal threads needing a bit of grease... as this was the cause of my latest BB noises

I will check these two things however, particularly for saddle rails, I'd expect noise under whilst under power which isn't happening. If it was the saddle rails, I'd expect the noise to be louder when I was going flat out rather than under lightish load

You have more weight on the saddle whilst soft pedaling, one of the reasons I tell people to pedal harder when they say the saddle is uncomfortable.

what bike is it, the reason i askis i had a similer noise on my mtb, it turned out to be one of the rear stay bushes had dried out, it always sounded like the chain, took me ages to find it,

It's a Giant SCR A1, largely carbon road bike. I think I'll just strip it down again at the weekend and see how I get on.

I had a similar metallic creak/clicking/ticking sound that was definately in time with pedal stroke. Started just out of the saddle under load but developed into anytime in moderate load.

Firstly I took out the bottom bracket. Press fit bearings had been pressed in dry. Took them out, lightly greased the outer casing a pressed back in. No change.

Then did two things at the same time, tightened the bolts holding the chain rings together (these were not exactly loose but not tight either) and removed the pedals and greased shoulders/threads.

Problem cured.

Now, my money is on the pedals here as the shoulders of the pedals were dry and there were definite signs of fretting where the steel pedal spindle shoulder contacted the alloy crank.

I'd read loads of stuff on forums and people saying check your pedals and I thought can't be that, they're tight as they are evert going to be but it wasn't just about them being tight.

I hope everybody is using a torque wrench.

And the winner is.......... new chain and cassette. Checked over everything else and then started looking at the things that would only happen in a narrow range of gears. Running like a dream now

I know you've solved it...and well done...but i had a similar creak, thought it was the cassette, then the crank even suspected the bars and post at one point.

swapped bikes .....and there it was again. turns out my shoes creak (not the cleats as such just the sole of the shoe)

FRUSTRATING!

I agree absolutely!! I've learnt over the last year that the one thing it usually isn't is the bottom bracket itself, although sometimes it might be. Drivetrain noises are my biggest bugbear and you can never tell where they are coming from. I once had one that I was convinced was the drivetrain and it turned out I'd over tightened the headset.
