The early RSX 7-sp was good stuff, the STI's are repairable and give many an older bike new life.
Some of them will NOT work with full size cranksets, as the smaller curve of the RSX FD cage fits the 48/36/26 crankset that came with a "compact" group. This makes them even more sought after by folks who want to tour in the mountainss. The "compact" triple RSX in 3x7 is a great setup.
