Sealed bearings into a cup and cone bb?
I'm working on building up my first project and had a bottom bracket question. I'm new at this, so this may not make much sense...
I got a good deal on a cup and cone loose-bearing sugino 75 bb off of ebay. I had wanted to go with a shimano, but this one matches my crankset and should give a perfect chainline. I'm in boston, where the weather can almost as crazy as the amount of salt and sand they throw on the streets.
I was wondering, can I buy sealed bearings to replace the loose bearings/retainer that I have now? I have a feeling that if I don't, I'll be servicing the bb a lot. And if I can't, how much grease to use? I recieved the thing with gobs of it in there. I always thought that it should just be a light coating...
