Slight clicking from bottom bracket/crank area...

Hey, guys.

A couple hundred miles ago I noticed a very slight clicking coming from the crank area somewhere, but only when I was really getting on it, like going up a steep hill or something. It's eventually evolved into a steady and more audible click, so now I can hear it with every pedal. It's not loud, but it's definitely there and I can hear it over road noise. I can't feel it.

It's nearly at the top of the stroke on the drive side crank.

What do you think it might be? Is my BB loose? I'm pretty new to bike maintenance...

Clicks like that could be anything. There's a pretty good trouble shooting list here:

Creaks, Clicks & Clunks...

I had a similar problem recently except that it was at the bottom of the drive side pedal stroke. I convinced myself that it was the Brooks saddle acting up, so I changed to a different saddle and it got worse. Then I thought surely it was something with the seatpost. I ruled that out and blamed the pedals. Switched those and it persisted. I finally removed the crank arms and bottom bracket and regreased everything. That got rid of it. A good bit of grit of grit had collected in my bottom bracket shell and the threads were sort of rough on one side, so I think that was it, but I've also read recently that ungreased square taper spindles can cause this kind of noise.

Do the easy things first. Try swapping your pedals with a known-quiet pair, preferably platform type to eliminate shoe and cleat noise. Clean and grease the pedal and crank threads and torque correctly.

I had the same problem last week. The bottom bracket bearing was shot. The LBS replaced them and it is smooth and quiet now.

Same problem here. My ride mates thought it was my knees but it was my right side pedal.

My saddle does that, just sayin'. Feels like it's coming from the crank/pedals though.

my buddy chased a BB click for 6 months, made countless adjustments, and finally found it in a pedal bearing - he swapped out pedals

I have had that it came from lack of maintenance on the BB. My friend helped we took the BB out bearing cups too cleaned and relubed everything and viola all better. He explained that the BB will flex slightly and things do move causing the noise that reverberates through the frame creating the audible click.

I have a similar issue with clicking & popping that sounds like it's coming from the BB but it doesn't do it all the time in every gear. In the 2 most often used gears is where I hear it most often, can that still be a BB issue ?

Thanks for the troubleshooting guide. I'm sure that'll be helpful.

I put the bike in my trainer with pretty high resistance and had my wife pedal. Pretty sure I've more or less got the location pegged at the chainring/bottom bracket area. I'll work through the trouble shooting guide and see if I can't take care of it myself.

It's possible. The problem with troubleshooting issues like this is that the noise can be dependent on a lot of hidden factors. For instance, you may shift your weight differently or maintain a different cadence in those gears that causes the noise to appear only then even though the gear selection isn't really the cause of the noise.

Thanks, I hope it is the BB. I've had more experience with them than with gear issues.
