Chain for Bianchi Pista

Hello all,

I have a Bianchi Pista that came with a KMC Z50 chain. When I looked up the specs for that chain I was a bit surprised to see it's 3/32" rather than the 1/4" chains I'm used to seeing. My last single speed (a State Bicycles) used the Z410. So my question is: does it make a difference? Are the chainring and cog really that much thinner that a thinner chain is required? Not a big issue, just curious. Thanks in advance!

I believe that the norm is 1/8" for the chain.

Yes, you're right. I meant 1/8". That what happens when I try doing math in my head... and my degree is in math.

the type of frame, track, road, mtb, is not always a good indication of the type of crank, road, track, mtb, or more to the point, chainring being used. it's the width of the chainring and cog(s) that's important. mixtures of 3/32" and 1/8" cogs and chainrings are compatible with a 1/8" chain. if BOTH the chainring and the cog is 3/32" a 3/32" chain be used. i'm no math major, but i think that's right.

BTW, a thinner chain (3/32") is not required for single speed under any reasonable condition i can think of, to give you a direct answer, which i seem to be incapable of doing.

somebody might have put a road bike chainring on there. wouldn't surprise me in the least.
