Boca Bearings Yellow Seal Ceramic are great for any weather
I've been a pretty loyal Boca customer for some time on the bike front. I think by now, all my wheels and all my BB30's are using yellow jacket ceramic bearings. I upgraded my PowerTap hubs and train on them all winter in the rain and grime. I've also used the BB30 ceramics on my cross bike through a very muddy season. I had to remove and clean them once and once serviced, they were as good as new.
