Bought a 057 from xmcarbon this winter and built it up this spring. 4 rides in a crack appeared in the center of the top tube.

Some correspondence and exchange of pictures with Peter and he is sending out a new frame. You would be hard pressed to get customer service like that from any American company. I had friends wait 6 months to replace their carbon frames from US companies. Disappointed the crack appeared but Peter was quick to rectify.
