I agree, the frame specs are identical; the only difference I can find is the layout of the cabling, the 970 moved the three rear cables to the top tube.

The improvement of the 1990 970 frame over the 1990 950 appears to be the layout of the cabling; the 970 routes three cables on the top tube. Trek notes this improvement in the 1990 catalog.
