Well I could measure to be certain as I have a T.A. Pro Vis triple on another bike and that uses a 127mm Shimano sealed bottom bracket. The crank arm bolts are right up to the bottom bracket, apparently the chain rings and arms are interchangeable with the same bolt pattern. Just looking at the chain line tells me it needs to be out further which is why I mentioned the 120mm. I have read Sheldon's information and 120mm has also been listed elsewhere.
