Strange noise coming from bottom bracket/crank I've just bought a Trek 6300 and I'm getting a strange creaking coming from the crank/bottom bracket when I'm stand pedalling. It only happens when I'm stand pedalling, and only what appears to be on my right hand side.  It's like a triple click on each downward motion on the right pedal.  But again, only when stand pedaling?

Any ideas?

I didn't buy the bike brand new from a shop, I bought it off of one a friend of a friend who used it for a charity ride in January and hasn't used it since, hence he sold it.  I just find it odd that the noise only happens on the right hand side.  Could it be that the chain is catching the front derailer?  I'm still relatively new to mountain bikes.
If you only just bought it from a shop, take it back and get them to sort it, but do ask what the problem was.

If you want to fix it yourself, it's worth determining the frequency and type of noise that you're hearing. I used this site when I had an issue similar to yours and I tried taking pedals off, the crank arm off and eventually took it to a bike shop and it was the bottom bracket that was making the noise.
