Hey Thomas,
I had the same problem as you. I got my bike in March this year from a LBS near my home in Switzerland. I took it back and had the bearings replaced by the dealer under warrenty. He used high quality SKF bearings sourced locally and supplied by the Swiss Intense importer. Since he changed them, I have had no problem at all and I'm very happy with the bike. Your frame has got to still be in the warrenty period. Can you not contact your supplier?
Ronnie.
