UPDATE!
First, thanks for the info Rpenmanparker concerning bearing selection. What kind of specialty tools if any would I need to replace the bearings in the housing?
Ordered the 6700 for less than $25 and installed. The 6700 BB was definately tighter on the spindle than the 8681 BB. Had to tap it with the palm of my hand to get it on. Once assembled the crank was definately tougher to turn. If I tried to spin it it would maybe only go 1 revolution. I then checked out the instructions and noticed if it was going on a triple (which it is) I needed a ring and spacer which typically comes with the crank.
I have not got a chance to troubleshoot it so I am not sure if it is tougher to turn due to being tighter on the spindle or if it is due to assembling without the spacer. Any thoughts? Also where might I get the ring and spacer, direct from FSA?
