    Slipping chain question

    I recently tried to change the chain on my road bike with a 7-speed sun tour freewheel and Dura Ace 7400 derailleur. I first tries a new SRAM 8 chain that is supposed to work with 7-speeds. Everything worked fine on the rack but chain slipped in almost all gears when applying any real pressure. I then tried a Shimano 7-speed Hyperglide chain and am having the same issue. Does anyone know of a chain that is compatible with Sun tour freewheels?

    You likely need a new freewheel, too. New chains often do not work with old freewheels.

    The freewheel is almost certainly shot.

    With Suntour freewheels, you can disassemble the sprockets from the body and and flip them around so the chain will ride on the unworn side of the cog's teeth. Unfortunately, the top threaded sprocket can't be reversed, so it'll still skip on that one.

    I got lucky with one bike this summer - did just the chain - but on another bike had to do both the chain and freewheel
    cycling is like baseball ~ it doesn't take much to make it interesting
