Recently my crank has been creaking when i stand up and sometimes when i sit down on it while riding, I have to tighten it alot and that only lasts for acouple rides and then I need to tighten it again to stop the noise. I was wondering what this could be and how to fix it, thanks.

After one weekend of downhilling on my new bike I noticed that I get "crank creak" when I stand up to pedal. Called my LBS and they said it could be a number of things- their advice was to make sure the all the chainring bolts are tight, make sure the cranks are tight, and then make sure the BB is tight. One trick they told me was that sometimes you can loosen the BB, rotate it like a half turn, then tighten it back up and it might stop the creak. I haven't tried any of this stuff as I am lacking the proper tools...

Of course their other option is to bring it back in for a warranty job (at least for me since my bike is only a month old...)

Anyway, don't know if that info helps you any as it seems it's your cranks that are giving you the creak problem- curious what type of cranks/BB setup are you running?

I am really not sure what Crank/BB's i am running i have a 2003 Trek 4300 ( i know its not that great but it does the job :) looking to upgrade when i save up the money) I just looked it up on the trek website the crankset is a Suntour XCC-150 42/34/24 if that helps you out at all. I think I might go to my LBS pretty soon just incase something is worn down or stripped. thanks
