Conditional clicking from back wheel This drives me nuts for months, I cannot figure out where the clicking sound comes from.
Only comes out after driving uphill, and not on the largest back gear, also not on smallest!
Only happens when I pedal with force, not when just follow slowly or backpedal.
The funny part that it settles down after I backpedal! (thus it cannot be spokes/wheel)
I don't see any dirt in the back derailleur, it has all teeth, but sounds like some consistent metal hitting metal.
I can only feel it via the frame not through the chain.
Chain is well lubed, no stiff links, super silent normally.
Back wheel and gear set is only ~6months old. Gear set is screw type not cassette.
Shifting is perfect. I tried to isolate the spokes so don't mind the paper.
Video with slow motion
It does seem to be in time with your pedalling. If this is the case in any gear, then it would indicate the issue is in the pedals, crank, bottom bracket area.
Check it isn't the front derailleur cable clicking on the right hand crank... rule out the easy one first! The mudguard too, anything that could be rubbing that shouldn't.
Then you would check the pedals, crankset and bottom bracket one by one. If you can swap out the pedals then you can isolate them and see if the problem goes away. Then check the crank bolts are tight and that the chainring bolts are too. Then if not solved you can pull the bottom bracket and inspect it for play in the bearings, replacing it if necessary.
btw, can't see in the video resolution but it almost looks like the front derailleur is incomplete? might want that replacing sometime. If that indicates the condition of the bike (poor) then the bottom bracket could well be worn out and be a strong contender for the noise.
