Getting bad creak on BBHSD in low mileage Cannondale Quick on down stroke of R/drive side.
No play, Bafang crank arm, regreased, retorqued crankarms , pedals and BB.
? Should I suspect an internal problem or just creaky device?

Also getting what felt like a chain skip under power, intermittently.
Good cogs, chain was OK but I replaced it anywho. no changes.
Replaced RD, checked hanger alignment, jockey wheels, frame, chainline. bearings spin OK
I suspect the freehub ratchet, which is a no name 9spd original

Any other suspected culprits. This appears early Shimano freehub with smaller pawls inside Freehub body.
 
Does it creak at the actual drive, or is the creak in the frame?

Most creaks I hear in stuff is from cracks being stressed, and eventually breaks.

The rest are usually from things rubbing against each other that shouldn't because they aren't as firmly secured as they should be.
 
No cracks in the Al frame or paint flaws I can find that could be frame troubles.
Something tells me this bike isn't Cannondale's best effort.
I know Creaks can be bedeviling and hard to localize, when the usual suspects are not found, or don't respond.
More trying to see if this is common with the BBSHD/BBxx.
I watched a bunch of Hambini, So I get how BB can have several spots that need a frame builder with sophisticated measurement skills to spot.

Thanks AW.
Hope things are going well for you.
