Im swapping components from my look carbon frame onto a colnago frame and i've gotten everything onto the new (old) bike apart from the crankset. What ive gotten stuck on is removing the crank arm locking cap. I guess its obvious but ive searched the web and found nothing. maybe im looking for the wrong thing. Anyway here is the picture, the crankset is dura ace fc-7701 and the cap i cant remove is the oone outside of the hex bolt.
