Bikes: Too many to list here!
I've got the Sturmey-Archer X-FD and the X-RD3, and I've ridden them in serious amounts of rain, without any trouble. Granted, I didn't dismantle them at the time to check if they were full of water, but I've taken the front one apart once due to problems with the shoes, and there was no sign of rust or dirt, apart from a bit of brake dust. I'm not certain they're "totally sealed", but they certainly work in pretty nasty conditions.
