10 to 1 it is not the frame ,,,, but your pedals,,,, just a thought...

seat post clamp or seat clamp. Don't over tighten either.

I dont want to be a prophet of doom, but I couldnt find the "creak" on my bike and it ended up being a crack on the rear stay. It was not easy to see. Check it out carefully especially where your rear disk brake connects to frame. Or if its a road bike then check whole rear stay for hairline cracks.

I have the same thing on my bike.

 

Checked the frame, oiled every thing. but it is still there.

Lose some weight.

I get a light creak every 3-4 pedal revolutions

Lose some weight.

 

thanx thats the plan????

Make sure the pedal axles are greased where they screw in to the crank arms. My carbon fiber road bike was creaking/ticking noise and I finally solved it by greasing the pedal axles.

Carbom? It's not creaking, it's ticking. But at least you get 1000 virgins at the end.

seat post clamp or seat clamp. Don't over tighten either.

 

Also check to see if it's not dirty and make sure the seatpost is not further out than the max

ask dr.phil

Grease the seat rails, if that does not work, put some grease on the fork stays.

But it is not the frame. Something just needs some lube or grease.

 

OR

 

If all else fails do what I tell everyone to do

 

Buy a set of earplugs.

Had the same problem with my bike for the last few weeks, took it to my lbs and they cleaned and greased the pivots where the rear shock attaches to the frame, no more squeaking. Apparently quite a bit of dirt gets in there!

I also had a creak on my bike a while ago. By sheer chance my brother also had the same problem and after chatting to him about it he said that he also had a Shimano crank with external bearings.

 

He suggested that I take the left crank arm off, clean the splines and grease them lightly. Afterwards put the arm back on and "finger-tighten" the center nut until the arm is all the way home. Then turn the center nut back half to three quarter turn and pull the crank arm towards the nut and tighten up the two "clamping bolts" to the recomended torque.

 

I tried it and voila!!!. I haven't had a creak since.

 

I think it has something to do with the end of the splines in the crank arm meshing with the end of the splines at the rear of the axle, where the most friction takes place under load.

 

I don't know what cranks you ride with, but if you have a crank with external bearings I would definitely suggest this quick fix before looking too far.
