Nope, the frame is straight and the BB is installed correctly. I measured the distance between crank arm ends on my road bike with Dura Ace 7700 cranks and it is exactly the same distance as on the 105 cranks, so it appears that the crankset and bottom bracket are fine. However, the distance between the outside of the chainstays is only about 110mm on my road bike, but it is 115+ on the K2, so I think knobster is right, I do need a longer spindle. Unfortunately, it seems my only choice is the 118mm triple BB if I want to use the 105 chainset (which I do).
