i have a steel frame which as suffered a horrible fate from watering pooling in the BB and seat chainstays. I was likely from being caught in the rain and not realizing water was running inside. After about 5-7 years it developed significant corrosion to the point where it is no longer safe to ride. Since fatbikes see much of their time in water and snow, won't I expect to see similar collections of water in the BB and seat stays?
