Creaking Noise

I developed a creaking noise recently while using road bike on a fluid trainer that only was present during riding out of saddle in higher gears.
Checked crank arm pinch bolts and pulled seat post out and re-lubed , but problem persisted.
Checked 105 cassette lock ring tightness with torque wrench and found it had loosen up about 3 notches. Torqued to 40nm.
Rode out of saddle in higher gears and creaking disappeared. A little surprised lock ring would loosen if torqued properly.
Checked my rear wheel that I use for road riding and 105 cassette lock ring was also loosened a couple of notches.

Moral of story check everything periodically even if torque to specs.

I developed a creaking noise recently when getting out of bed in the morning. My girlfriend told me to man up and stop whining

Sounds like you need to get torque to specs

Those cassette lockrings have the clicking detents which, IMHO, interfere with an accurate torque reading.

Another variable is if the threads are greased or dry. 40Nm on a greased thread will produce more clamping force than 40Nm on dry threads.

But your point is well taken, it doesn’t hurt to check torque once in a while.
