Yup. I’m dealing with noise every pedal stroke on my MTB. Be process of elimination, I ruled out other causes. Took the crank off, and sure enough, there’s a rough spot on the left side bearing.
My press fit BBs on my MTB have lasted about 2.5 years each. 6 mos seems short. But maybe possible if the BB was not installed correctly? Good news is that press for BBs are not expensive. My replacement cost $35. It’s sitting on my workbench. I’m trying to decide if I should finally get a BB tool, or just use my rubber mallet again
