As the post suggests, I just installed a new crankset and bottom bracket with external bearings. The crankset is an FSA K Force compact, and the bottom bracket is the corresponding MegaExo external. My bottom shell measures 70mm. I greased everything up really well and I made sure the cups and internal spacer sleeve thign was installed straight and properly. I wasn't grinding any threads on the way in. Anyway, it turns really smoothly but it doesn't want to spin really freely if I give it a spin (with no chain yet installed). I don;t hear any grinding or feel and bearing ceasing. It's really smooth but my old bracket would spin for about 15 seconds and then come to a rest on the drive side back and forth. So do you believe that something is wrong? Should the crank be able to be spun 30 times around with one push of the crank arm or will it break itself in? I am sorry for the rough explanation. Please ask any questions you need to fully understand.
Also, I have a 2mm washer spacer but the middle spacer said "68/70mm" and my bottom shell measures 70mm so I shouldn't need that, yeah?
Thanks in advance.
