Hi, I've got a Phil bottom bracket with about 10,000 miles over three years that I noticed was
turning rough and almost sounded dry. Figuring that I didn't have much to lose, I pulled it, popped
off the seals on the bearings, cleaned and re-greased them. It now seems a lot better- not perfect
but much improved. It's on a road bike that I generally don't ride under dirty conditions and is
very rarely in rain or wet- only when I get really surprised. I have weighed in the 270-290 lb range
most of the time I've owned this BB.
My questions: I've always kind of assumed that sealed bearings could just be ignored- nothing needed
to be done and the Phil's would last almost forever but I'm beginning to question this. Should I
have some kind of schedule to open, clean and grease these guys? Also, as I look at the seals, they
would keep most of the grease in, but I'm not so sure they can keep dirt out?
Thanks in advance. Lyle
