    Six speed compatability between Campy and Suntour?

    I have a wonderful Bill Davidson touring bike built up with an early-90s Campy MTB gruppo. To my amazement, I found when the freewheel finally wore out after about six years of use (on only two cogs, of course), that the freewheel is a Suntour Winner! Is that even POSSIBLE? The bike was a gift from a dear friend in Kansas, so I don't know if the freewheel was reconfigured or not. Anyway -- does it follow that a non-hybridized Suntour freewheel would be compatible with early-90s Campy index shifting?

    friction shifting makes all sorts of mismatches work fine ..

    I have a Campag Euclid RD on my touring bike ,
    and Sun Tour power ratchet non indexed bar end shifters..
    20 years of reliable methodic shifting..

    6 & 7 speed Freewheels , no problem..

    Here's a more-detailed version of DCB0's link: http://sheldonbrown.com/cribsheet-spacing.html

    When in doubt, go friction.

    Thanks, everyone. I'd found the Sheldon Brown chart, but I doubted it. Shame on me for doing so.

    I settled for a SunRace -- cheap, but accessible. I'll keep trolling eBay for better.

    Just replace the cogs. Suntour Winner Bodies are basically unbreakable. The tooth shape is not really optimized to pick up and pass the chain to the next largest cog over more than about a 3 or 4 tooth jump, but if you can live with the lazy shifting, they are good freewheels. Cogs show up on eBay every single day.

    Thanks, Captain. I have decided to do so. The replacement is only temporary. At first, I was disappointed that the freewheel is not Campy, but the Suntour Winner is pretty awesome!

    In all her beauty. The stock foam handlebar covers have since been replaced by white Cinelli cork.
