We really don't know how many miles on her BB. We bought the bike from the 2nd owner a few years ago. She hadn't ridden it much & said the original owner had only toured a bit before selling it. My wife has put a few thousand miles on the bike but I doubt it has over 10,000 total. I bought my Atlantis in early '03, and the SN is a bit higher but then a 47 cm frame could have sat around for a few years before selling. My original BB went about 25,000 miles. Both bikes have always been in a fairly dry climate although mine has seen it's share of water on trips. I'm thinking time may have allowed the grease in hers to dry up, leading to an otherwise premature demise. Both BBs were the Tange that Rivendell installed as OEM. Since my bike has well over 50,000 miles, I was actually expecting to replace the Shimano BB it but it turns easily and doesn't make expensive noises. I may replace it anyway next time I have the cranks off.
