I'm not sure what I'm doing wrong but yet another shimano bb has become very stiff after only a few rides. I have to imagine this is an issue on my part as it has happened a few times now. I usually hose down bike after riding but purposely avoid any jet like settings on the hose gun and don't aim it at the bb shell area. Also don't power wash it btw. Is it possible that not drying it thoroughly enough and leaving it in the garage is allowing water to trickle into the bearings and causing them to seize?
Standard deore outboard bb like this
