Subject: RSX shifter for 7 speed cassette Posted by: Randy on December 07, 2000 at 23:17:53:

Message: I have an old Klein Quantum with 7 speed Shimano 600 groupo. It has shift on the downtube, now. Will the RSX STI shifter (states that it is 8 speed compatible) work as a replacement, or is there an older version for 7 speed only?
