If cleaning off the bottom bracket spindle in End that Crankarm Click didn’t solve your noise, its about time to pull the bottom bracket out of the frame.

Sometimes water can get into your bottom bracket shell and work its way into the threads, dragging crud with it and making that creaky click happen. Using the correct tools for the given bottom bracket, take it out of the frame and clean up the threads, both the frame and bottom bracket cups. Get all of the old grease and contaminants clean of the threads, load it up with fresh high quality, water-proof grease and put it all back together. Might even want to try wrapping the threads in some plumbers tape.

If all of this cleaning and regreasing still hasn’t solved a click in your pedal stroke, it’s time to continue trying to diagnose the problem. Sure its coming from the crankarms and not somewhere else? It could be the pedals, it could be the bars, it could be a crack giving you a warning, or it could still be that pesky bottom bracket. I’d suggest removing parts from the bike and trying to recreate the noise without wheels, bars etc. And give those crankarms and frame a good inspection for cracks, just in case thats what you hear creaking.
