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...
'''96 Litespeed Catalyst, '05 Litespeed Firenze, '06 Litespeed Tuscany, '12 Surly Pacer, All are 3x8,9 or 10. It is hilly around here!
Again reinforcing the grease recommendation. Too much is barely enough. You want the excess to ooze out so it forms a bit of a seal that way.
Also, you can get a corregated plastic sleeve that goes into the bottom bracket shell between the cups and helps keep crud and water away from the bearings. These things are less than $1 at almost any LBS.
Use the Suguino and when it dies, then get a sealed bb.
