Hello,

I have a Boardman Comp (Aluminium frame) size large. It has a Truvativ GXP bottom bracket with Truvativ Elita cranks.

When I put the bottom bracket under a lot of strain (going up hills, standing on the pedals) I hear a lot of creaking. Is this the frame flexing or something else. I can't quite figure out what the noise is? Can it be reduced somehow?
