I fitted a mega exo crankset last year

It creaks when each pedal reches between 1 and 2 o'clock when pedaling (if viewed from drive side... 10-11 o'clock if viewed from non drive side)

Read the park tool guide, removed the cranks regreased the crank shaft and where the non drive side crank fits and its got a bit quieter but still there...

it does it in each chain ring so I cant see it being the chain ring bolts?

Any ideas?

    so you think it is the bb? replace it.

    its eased up since I greased up the shaft but used that much grease that there is a bead of it between the crank and the bottom bracket outer seal. I've not done that many miles on it and dont want to have to keep replacing the BB.

    The bb doest feel like its grinding, there is just theres a little creak when I pedal (used to be louder before I re-greased it.)
