Really? I wouldn't think it would be that much of an issue. I understand not wanting to ride through because you don't know what's under there, or how deep it is (and up to axles and bottom bracket is pretty damn deep), but why would that make you need to service the acleas and BB when it's standing fresh water? I would think you would do more damage riding through a driving rain for a while, or with a bike on a car-top rack in the pouring rain.
