There is a clicking noise coming from the BB area when I am riding out of saddle. I have a Dura Ace outboard BB. I removed the crank and when I turn the bearings with my fingers they feel ok, but there obviously is no load on them. Is there a way to tell if the bearings are the source of noise other than replacing them?

I mean the tool for the actual bottom bracket bearings. And as far as the pinch bolts, I'm very careful not to over-torque. As it turns out I was too careful, hence the clicking. Gently snugging them up a bit quieted them down.

Yikes...ya mean the little cuircular tool used to install the left cranarm? That is intended to me finger tight, no more. If you do use a seatpost for leverage, you run the risk of killing the left bearing AND proper torque on the pinch boilts is essential. or you can kill the left arm.

Clicking outboard bearing BBs/cranks very common. DO NOT just gun the left arm pinch bolts in..ya can kill the left rank arm that way..use a torque wrench.

It actually turned out that the pinch bolts on the left crankarm simply needed a little more tightening. I'd been wary of over- tightening them--too wary, as it turns out. Snugging them up solved the problem. If that doesn't work and it's not your pedals or something I'd pull the BB, grease, and reinstall. If you're using the Shimano-supplied BB tool it can be tough to get them tight enough without using an old seatpost for leverage or something.

They're Miche quill pedals. I'm not sure if they're original to the bike they came to me on (Fuji Roubaix with '89 or '90 Shimano 105. The pedals were the only Italian part on the thing) but they are pretty well worn. When the bike came into my posession I took them apart to clean and grease the bearings and the spindles seemed fine at that point, but that would have been six or seven months ago and I'm apparently a bit of a gorilla.

I'll have to try and remember that as it has never occured to me and I'd never think to look for that- care to name the pedal that broke ?

I pulled the bottom bracket, inspected, cleaned, and reinstalled it with grease and loctite in the appropriate places. The sound went away. Then last Sunday I broke the right pedal spindle and got dumped in a busy intersection. I think right around the time I was working on the BB some grease got into the cracked area and silenced it. (Crack was just outboard of the inner bearing race.) After waiting at the light with no cars coming in any direction I had decided to run the red since it's a very sketchy intersection, so luckily when I hit the pavement I wasn't in danger of being run over. Plenty of witnesses though, unfortunately. Be careful and thorough in checking for cracks.
