sound on every right pedal stroke??
when i am off the saddle sprinting or blasting up a hill my bike makes a terrible creak sound on every right peddle stroke at the bottom. I have read that it is probaby my right pedal/cleat but what do i do to check it? I also have seen that it could be a bad BB that needs greasing or even a cracked BB area?? kinda freaking out a bit.. suggestions?
its really embarrasing when you are cranking it past someone with this nasty sound radiating from your bike.

You'll love this one, simply because it just goes to show that where you think the sound is from isn't always where it is.
Have a Trek that exhibited very similar behavior to yours. Tore the crank, BB, pedals , cleats apart on several trips out Nothing made it go away. Thought maybe I was going nuts, and had a friend ride beside me for several miles. We both *swore* the sound was coming from the BB. Only on the right pedal stroke, and the same place in the rotation, and only under load.
Decided to broaden the search... know what it was?
Insufficient assembly compound on the carbon seatpost and it was creaking in the seat tube. I had hours in the search before I found it.
Where the sound sounds like it's coming from isn't always where it is.... keep that in mind.

I may be completely off (as per the previous poster) but PLEASE double check your pedals to make sure they are tight. Once upon a time I cheaped out on a pedal wrench because I had one but it was at my parents' house. I never got it, left my pedals as they were, and ultimately had to spend $150 on a new crankset because the threads sheared off and I couldn't find a left-only crank arm for that crankset. That's chump change for some of you, but I'm a broke-ass college student and at the time it kinda sucked.

I had that sound. It was my BB flexing and pushing my chain into the FD. It was a square taper into a crappy FSA crankset, doubt it was the frame. New bike has Hollowtech BB and 105 crankset and I never hear it.
