I'm having to change the BB on my cross bike every 6 months or so, I've used some of the Shimano range, and the more expensive ones dont seem to last any longer than the cheaper ones (ukp 15 to 30ish). My most recent BB was a Campy, cannot recall which model, but now that is showing a bit of play - it is always the bearings that start wearing.
Any recommendations for a decent BB that will last a bit longer, or has replaceable bearings, or should I stick with the cheapies, and change them when they wear out? Thanks Alan. -- To reply by e-mail, change the ' + ' to 'plus'.
You can replace the bearings in the Campy BB, they're very reasonble. I've seen the original Campy versions for sale on EBay for around $10.
The real question is, why are you going through BB's so fast? Maybe it's a problem with your BB being off as far as the threading goes? I typically go 3-4 years on a Campy BB, even on my rain bike here in Seattle; it gets usually several thousand rainy miles/year.

I've wondered this myself,a nd after taking out this old BB, found it was an expensive FSA Titanium, which I promptly ruined when I tried to undo it - I resorted to a cold chisel and hammer to remove it when it wouldnt shift. When removed, it was obvious why it had worn - the outer bearing shells are sealed, but the internal ones were open, so water had seeped into the gap in the centre tube, got into the bearings, and they were shot quickly. I've gone for the cheap route now, mainly as the LBS only had this one in stock (a Stronglight, supposedly sealed for life, and twice the weight of the old one).

To get it out of the frame? Yikes.

Well, you could stop the water ingress I suppose. Seal up the slot at the top of the seat tube for the seat post pinch bolt (grease works, beeswax works too). Install a rear fender. Drill a drainage hole in the very bottom of the bottom bracket to let the water run out. Stop swimming with your bike. ;-)

Hmmm. I've managed to ruin a Phil Wood twice on my commuter. After the first rebuild I just put a Shimano sealed unit in there. At the price, I was losing money on the Phil Wood rebuilds.

I jave over 51 thousand miles on mine, all original equipment an it's still going stong.
