I have a 14 Giant TCR, bought last September. Exact same thing happened to me. After the 4 spoke broke, my Lbs re-laced the whole wheel. I have about 500-600 miles on the rebuild and just had to take it back this last week because two spokes came loose on a 50 miler on Thursday. I rode 85 miles and climbed 5800 feet the last two days and so good so far. I can't find any answers either**********
