Has anyone had premature failure problems with their PF30 BBs? I picked up my new RSL 29er with a PF30 BB back in the fall and within 2 months the BB failed. When my LBS removed the BB they said water had gotten into the BB and caused the failure so it would not be warrantied. They showed me the bearings and you could see rust coming out the bearing race on the non drive side bearing which they said is more vulnerable to contamination given it is more exposed to the elements on the non drive side. They replaced the part at cost with no labor charge so I didn't worrry about it much and tried to be more careful with the new BB in terms of exposure to mud and water. Was working on my 29er last night and sure enough the 2nd BB has failed. Haven't tore the crankset down yet but now I'm frustrated. I did ride yesterday and the conditions were wet and muddy so I bailed on the ride just 45 minutes after getting out so the BB area was in the soup for a bit but I never had a problem with premature failure of cartridge BBs in this type of a siuation so I'm very surprised at how delicate / susceptable to water this design is. The bike was also used on a few other outings when it was a bit wet and muddy but nothing too extreme and again the cartridge style BBs I have used never seemed to be problematic in these situations. My only other concern is that perhaps the bearings are not aligning properly when installed and this is the actual root cause problem behind the failure? Thoughts?? Are there better PB30 BBs that I could try that have better seals / more weather resistant?
