Hello, this week my bike has developed a creaking noise from the crank area. I have checked it over to make sure nothing has come loose, and even torque tested the bolts for overtightness.
The noise only happens when pedalling not during freewheel
Any ideas ??

Could be anything!!!
I had a creak from my Crank a month ago.....
I Stripped the BB and it was fine
Was told that the seat post can creak and 'throw' the noise. so it sounds like its at the BB. My coach had this problem once, he spent 6 weeks searching for the noise then one day lent on his saddle and 'The Noise' came about!! lol
I tried a different rear wheel and ALAS no noise!!!
therefore something on that rear wheel was causing the noise.
I was running a SRAM Red cassette on that wheel through a Shimano DA Set up..... so I changed the cassette to a SRAM Force cassette and the noise was quieter but still there....
I then swapped the SRAM cassette for a Shimano cassette and NO NOISE!!!
So it was deffo something with the SRAM Cassettes.... I then tested the SRAM cassettes through a SRAM Red Groupset and the noise was still there???
It actually came out that my rear derailleur on both bikes weren't quite lined up and due to the constructional differences between Shimano and SRAM the chain wasn't running quite true:)
So lesson learned from my experience is that just because the noise appears to come from the Crank/BB it doesn't always mean its actually there thats the problem.......
If your bike is in good order then you can possibly ignore it and it might go away - as errant bearings bed down. However it can be really annoying and if you are not a regular servicer then get it seen to. Bring it to your LBS or remve the BB or crank arrangement and grease it
If it's a high pitched clicking type noise, then it's more likely that it's the BB. But as posted above, take apart, grease, and see what happens...
