I need some advice. Im trying to swap over my cranks from truvativ stylo to shimano xt. Ive gotten the cranks off, and I'm trying to remove the external GXP BB. Ive got a park tools external cup remover tool thing which fits the notches on the external cups perfectly. I have checked to make sure I am undoing the cups (checked the arrow on each cup) but I cannot get them to budge.
Any advice? i have tried tapping it with the rubber mallet too but that didnt acheive anything. I have seriously put all my body weight into this and the bloody things wont move. Any tips?
They were installed by my LBS about 9-12 months ago so I assume they greased the threads etc correctly.
