Remedy for cracking sounds and noises
Noises can occur where parts join, for example on weld seams or screw joints. Carbon fibre frames might emit very loud noises, although these can normally be located and eliminated very quickly and easily.
Disassemble the pedals and apply grease to the threads.
Picture 1 Re-tighten the pedals after the first ride. You need to check, if the screws of the shoe-cleats are tightened with the correct torque. Apply some grease to the cleats and replace worn out cleats at an early stage. If the pedals have screws, apply some grease to this contact point to avoid creaking.Picture 2

2. Quick Releases
Make sure that the quick releases are closed and tightened with sufficient force.
Picture 3 Make sure that through axles are correctly closed and greased.
3. Saddle and Seatpost
Check if the seat clamp is tightened with the correct torque. You should check as well if the seat post is sufficiently inserted into the seat tube. There should be enough grease on the post if frame and post are made of aluminium. If the seatpost or frame are made of carbon fibre, do not apply grease to either of these components. Instead, use carbon assembly paste.
You need to check the head of the seatpost as well.
Picture 4 Seatposts with a head made of titanium are liable to creaking sounds. You can prevent noises by spraying wax on this contact point.
4. Rear Derailleur Hanger
The rear derailleur hanger is often the source of noises. Dismantle the hanger and apply grease to the contact surfaces.
Check if stem, brake levers, and gear shifters are tightened with the correct torque. Only apply carbon assembly paste to parts which are made of carbon fibre.
If your shift cables are positioned inside the frame, there might be noise from the point where the cables enter the frame. Apply some grease to these contact points.
7. Bottle and Bottle Holder
Check if the bottle cage screws are tightened with the correct torque.
8. Chainring Screws
Check if the chainring screws are tightened with the correct torque as well.
