Click, click, click.... Bottom Bracket?

My bike started a very obnoxious rythmic clicking at mile 63 of our century today. Everytime I turned the pedal (when my foot was down) there it was. I want seem borderline intelligent when the wrenches are talking to me, it is quite possibly the bottom bracket right?

I had this exact problem about 6-7 months ago. The bike only clicked when I was pedaling, didn't matter what gear I was in, just click-click-click 80x/min on every ride. I ignored it for a week or two because I had been meaning to get a tune-up anyway, but then I did a 60-mile charity ride where the click was driving me batty by mile 30. I gave in and checked with the mechanic at one of the rest stops. After eliminating everything else on the bike (not even sure he heard the clicking while it was on the stand--I couldn't hear it from where I was standing), he did think it was the bottom bracket. Since there was not much he could do in the field, I just rode the rest of the route and took it to my LBS the next day for a tune-up and asked them to clean and re-pack the bottom bracket also (the field guy's advice).

They did that, I took it home, and it was still clicking. Through some trial and error, I figured out that when I unclipped one foot, the click was either much quieter or went away completely. Also, it didn't click at all when I rode in the rain. That made me think it was the pedals (SPDs) or the cleats, and it probably wasn't the cleats because I tried with two different pairs of shoes. This went on for another few days until I scheduled another service appointment. On that one, they figured out that it was indeed the pedals that were causing the click. I replaced them, and the problem went away.

So, yeah, it may well be the bottom bracket, but it wouldn't be a bad idea to check your pedals too.

Pedals are a definite possibility. Try pedaling by putting pressure with only one foot for a few strokes and see if the noise goes away. Or swap out the pedals.

I had the same issue. LBS thought it was the cranks so they tightened them and sent me on my way.

I swear that the clicking got worse!

Then I ordered a new bottom bracket and replaced it...clicking remained.

I switched pedals with my husband, and sure enough, that was it. I was ready to buy new pedals when DH suggest I re-grease mine. It worked! So I put my old bottom bracket back on it (sold the new one on ebay), put the regreased pedals back, and made a mental note to try the easiest solutions FIRST next time.

Moral of the story: check the pedals, first. It might be an easy fix.

There can be a lot of clicks caused when you are pedaling, so look for really obvious (Or not so obvious things). My old bike used to click and I thought it was the loose stuff rattling around in my pedals (they did this from the first day I bought them so I kind of ignored the click).

Then one day I was looking closely at the bike and realized that the little end cap on the cable for the derailleur was hitting the pedal arm every time I pedaled!

Yikes, talk about obvious!

I always look for loose duct tape on my bike

Is there any certain type of pedals this happens on? My Look pedals are only 3 months old and I don't know where you would grease them. My DH had the clicking problem with Speedplays, but I am not sure where to start with my pedals.

Chimes in with another non-bottom bracket click - I get a creak-click that sounds like someone dropping a ball bearing if I don't periodically reseat/tighten the quick release on my rear wheel. It was driving me bonkers. I had my LBS tighten the BB too - he did say one side (its and external BB) was a bit loose, but the creak remained until I tightened up that rear QR.

My husbands TT bike definitely has a loose BB - the sound it makes is a very loud snaping noise.
