The above commenters are correct that the plastic cup actually works pretty well, even when cracked. The plastic cups are the source of much hand-wringing (despite being functionally just fine), which I suspect led to Shimano changing to the metal cup on the newer model (according to a previous commenter).
Don't waste money on a Phil BB. IME, the Phil bearings don't last any longer than the Shimano cartridge, and they cost more to replace. In other words, your initial $150 investment doesn't translate to savings down the road. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
