There can be two press fit complications with the BB30

This results in a creaking sound. To resolve this, first check the torque on crank bolts to determine if the crank-to-spindle interface is the source of the noise. If this fails and there is still creaking, it may be the cartridge bearing moving in the shell. The b…
