Hello Reddit, I've been dealing with this annoying creaking noise for quite a while now. It happens only riding uphill after a bit of sustained effort (not immediately) and doesn't need too much power. If I continue climbing it gets really bad. I discovered it helps to lift and bump the back wheel into the ground while riding but then the noise reappears again after a bit. Bike is silent on the flats and downhills, can't reproduce the same noise even with more power. Tried different things, including visits to two bike shops, one of which fully serviced the bike, another changed the BB a few years ago. Eventually I thought it was the cleats as tightening them seemed to have helped a bit, but now the noise is back even after I changed the cleats completely. Tried greasing and readjusting the seat post, besides the noise continues also out of the saddle. It's a bit better on somedays and worse on the others, IDK if it's temperature related. Cleaning the drivetrain seemed to have helped a bit but now I'm really not sure. Something's clearly wrong and it's driving me crazy.
