Nope. Have an SL6. I have ridden in the rain. After getting home when I went to hand the bike upside down water drained our of the frame. I put the bike back down on its wheel. A little more water came out. Then found a tiny drain hole on the bottom of the bottom bracket. But there appears to be a plastic film inside blocking the hole. Poked at it and water came out. So may have started with the water. For the new bearings did you grease the threads? May be that.
