Sounds like your crank bearing. I had the same problem. It would only do it while I was riding. Drove me crazy. If it happens every crank rotation, this could be culprit

I had the same problem for daysss , now i took the bolt out of my crank which connects it with the spindle and used some copper grease on it and it was finally gone

Chainline is important, more so for modern 10+ speed systems. A six speed system is more forgiving of misalignment than one would guess. Since both BB are square taper all you need to do is remove it and see what the size is on the BB itself. The shaft will only allow a crank on so far (that's why its taper). By buying the size currently in the bike you ...

I had a similar noise coming from what I thought was the cranks or the chainset. After taking it all apart, re-greasing it all and also replacing the bottom bracket the noise persisted to my frustration. It turns out that although tight enough to hold the wheel in place, the rear quick release was not tight enough. Hey presto, once I tightened the QR the ...

I was able to get the collet off with some gentle tapping from a screwdriver and a hammer. The collet is a soft metal, my screwdriver definitely made a mess of the metal. If someone in the future has the same problem, use some sort of hard plastic to buffer the hits. I did try to bash it out by reassembling everything and applying wood + hammer to the ...

From what can tell from the photos it looks like the inner race is seized to the crank axle. When you removed the non drive side bearing did the ball bearings fall out? You can try to carefully cut the race off with a Dremel with a cut off wheel. You must be very careful not to go too deep and hit the crank axle. I would cut 9/10th of the way through. Then ...

I would try reinstalling the drive side and non drive side cups to the frame (to keep the spindle centered). Then I would recommend a game of whack-a-mole on the spindle with a rubber mallet. I have often had to remove a crankset this way. A rubber mallet should be in pretty much any home mechanics tool kit. The rubber mallet has almost no chance of ...

Remember, there are two bearings in the BB, and it is possible to have one go bad/move around while the other is steady. Bearings can shift in their housing, rust on their external cups, rust internally, you name it. BikeRadar has an excellent article on them: http://www.bikeradar.com/us/gear/article/workshop-how-to-service-bb30-press-fit-bottom-brackets-...

Just a guess, is the bike a Cervelo? They are notorious for creaking, but are hardly unique. I agree with the above comment about bearing movement inside of the frame. It is maddening. There are several ways to solve this: Instructions: Do not go back to the LBS you've used earlier. Nothing mean but they seem to lack the experience to figure this out, ...
