I have a 07 595 Ultra frame set and recently brought it to my LBS for the full build up. The mechanic at the LBS called and said that the left hand side bottom bracket cup would only go in 3/4 of the way, and then totally freeze. He has tried everything even using a tap, but still no luck (the right side threads in just fine). The LBS has tried to contact Look but so far no response. If anyone out there can help I would really appreciate it. The frame is brand new, so my only thought is some kind of factory defect on the left hand side bottom bracket insert.
