I have developed an annoying squeak in my drivetrain. I believe I've localized it to either the BB/crankset or RD pulley wheels since it only occurs under power and doing a thorough cassette/chain cleaning and re-lube fails to cure it. It seems more pronounced in the {small ring—larger cogs} combos but still present in others.
Unfortunately, I can't localize the sound with the bike on the stand since it apparently requires more force than I can deliver by hand.
My plan is to first remove the chain and lube the jockey wheels, and if that doesn't eliminate the sound then remove the cranks and re-lube the BB cups. I built it up in November and thought I was pretty careful applying grease in the cups at the time, but perhaps I should have been more generous.
If you pals have other potential suggestions for investigation I'd like to hear 'em since I don't have a torque wrench that goes to 40+ Nm, which means that crankset removal will then require a trip to the LBS.
Thanks

A ‘squeak’? I’m guessing chain dry or pulleys, lotsa grease inside those. Doubt it’s the BB.
