Problems with BB30

How many BBs would you expect to wear out in the time this bike has been on the road, even if you were a high mileage wet weather rider? Any reasonable BB would shrug off 5 months of serious abuse.

Ah - the mistake here is confusing BB30 with a 'reasonable bb'.

BB30 is clever, but if we measure bb effectiveness with its ability to put up with the good ol British weather, the design comes up short.

So if you put in 300 miles in the poring rain and don't dry the thing out, and it gums up because water has got into the bearings, you can't really claim SOGA as it's performing exactly how it was designed to.
