Anyone have any experience with life expectancy on sealed cartridge bearings? My Soma Somax rear hub stock bearings were toast after less than 2400 miles, and I replaced them with bearings through my LBS, and now they are getting crunchy after about 1000 miles. I do ride the bike in New York winters, but clean after use, and still have the original Excess freewheel, which has seen the same conditions, operating just fine.
The hub bearings are small (6000's), and I picked up some Enduro ABEC-5 bearings for, but I am wondering if I should just pull the hub and lace the rim with something more durable. I have Surly new ultra hubs in a different wheel set, and they seem solid, but only have a few hundred miles on them.
Thanks for any insight / experience.
