    Hi all,
    I'm new the to forum and was hoping for some advice/help. I'm riding a 02' trek 5900 kyrsium sl's and under load there is an annoying rubbing in the drivetrain. It happens in all gears and is most noticeable when seated and climbing. My LBS seems to think it is chain rub, but inspected the front der. to death and no way is the chain rubbing the der. My initial thought was BB, but I have a brand new Dura Ace Track BB installed. Does anyone have any thoughts?? It's not a constant rub only under a hard load and only on about a third of the rotation.

    Thanks for any help!!!
