Thanks for the heads up, this is valuable to know!

Is this the BB you are using?:
VeloBase.com - Component: Shimano BB-7400, Dura-Ace so it would be ~112mm. Can you please measure your chainline with a ruler or similar? See Sheldon for instructions:
http://sheldonbrown.com/chainline.html Here is an excerpt:Simply hold the ruler against the seat tube or down tube and measure the distance from the middle of the seat tube to the middle of the chainring teeth. In the case of triple chainwheel sets, measure to the middle chainring. In the case of doubles, measure to the halfway point between the two rings.

Thanks for sharing this link. I asked the seller but s/he seems clueless about it.
