The gritty feeling I felt, is nice to know that I can loosen the adjustable cup, to make it go away. Tomorrow I will take the BB back out and put more grease on it, just to be on the safe side. The LBS had already greased it after cleaning it and placed it in a zip-loc bag to keep dirt off the unit itself.
Thanks Bill.
What Bill was referring to is how tight the adjustable cup is. When you thread it on it should be tight enough so that the spindle doesn't rock but not so tight that the spindle binds or feels gritty. This is a touch thing that usually takes a few tries. When you first tension the bearings the spindle may feel free to spin, but when you tighten the lock ring it sometimes over tightens the cup. You then need to loosen the lock ring and try again. Even if you manage to hold the cup in place when tightening the lockring, the mere force of tightening down the lockring will change the tension; it usually takes me a few tries before I get the tension (or preload) where I want it. See if you can let off some of the cup tension to quiet down the bearings.
