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?...................................................................>>...The original RSX was 7 speed, and there was a later 8 speed version .The 7 speed would shift a double or a triple on the front, but the 8 pseed was double or triple specific. Check www.harriscyclery.com for the seven speed version. Any 8 speed shimano STI other than dura ace will also usually shift a 7 speed cogset even though the spacing is different than 8 speed.It's close enough to work. Shimano may also be marketing a seven speed version of the Sora shifter: check with harris cyclery.
