6-speed rear shifters(6 posts)

Does anyone know of an STI type shifter that would work with an older ( much older) 6 speed rear. Alternately, would a 7 speed rear cassette fit on a 6 speed campy hub? My only other option is to rebuild the wheels and replace the drivetrain - too much $$$$$

If you'll settle for bar-end shifters (I love mine), all Shimano bar-ends have a friction option. That means no indexing, but it's fairly cheap.
Also, some early STI stuff is starting to show up either used (newspaper classifieds) or beat to crap (Salvation Army and other thrift shops). I found a $40 Bridgestone in a thrift shop and scored a bunch of 7-speed stuff for my wife's neglected road bike not long ago. A little cleaning and adjustment, and it works fine.

6-sp. sti will workclub

just use narrow spacers between the 6 cogs (old 6 sp. spacers are wider) and fill in behind the large cog with more spacer(s) so you can get the cogs tight on the body. Then adjust the low limit derailleur screw so you can't access the additional clicks. You can do this with any number of cogs, you could make a 2 sp. with sti if you want.

If he has the narrow 6 speed spacing,it's the same as 7 speed and 7 speed RSX STI will work.

I think you're off by a gear. Narrow 6 fit in 5 speed spacing, 7 (which was always "narrow") fit in 6 speed spacing. This guy is proposing putting 7 in where 6 was, should be no/minor change. He may need an extra 1mm washer on the derailleur side of the hub. Also, this is almost certainly a freewheel hub, not a cassette hub, so forget the "spacer" stuff and just thread on a 7 spd freewheel.
