    chain for 5 speed rear freewheel

    Probably a pretty easy question here.

    I need a couple of chains for a couple of old road bikes im working on. Both are standard 10 speeds with 5 gears in the rear and friction shifters.

    Would i be ok running a Sram 870 or 850 chain? They are listed as a 6/7/8 speed chain. I cant find much for 5 speed chains......only single speed and the 6/7/8

    All derailer chains are the same width on the inside of the plates, or very close to it. A standard 6/7/8 speed chain will work fine.

    Yep. Just don't use 9 or 10 speed chain. More wear, and it might not play well with the possibly wider teeth of an old 5 speed freewheel.
    Why "derailer" is the correct way to spell the gear-change mechanism: sheldonbrown.com/derailer.html

    for the OP, the basic theme a 3/ 32 bushing less chain will do , the 5,6,7,8.

    But 9 starts thinning down internal spacing, thinner roller and pins,
    to add a cog without widening the cluster..
    ditto and more so with 10 and 11, still a 130 wide axle , after all..

    check your local shop for KMC chains. a place close to me sells a nice chain for only 9 pounds, for an extra few quid you can get a sexxy silver one.
