Creaking bottom bracket
Take the shell off of each side of that bottom bracket and grease each one up, along with the spindle. When you tighten that bottom bracket back on, don't over torque it or under torque it, if you over torque or under torque that bad boy is going to squeak. If you aren't sure of the torque or you don't have a torque wrench, visit your local shop.
