• Time to change the chain on my Day One.

    Currently fitted with a kmc (I think) 8 speed chain but every other bike I have runs a kmc 510 (1/8" singlespeed chain).

    Do I switch to a 510 on the Day One so it's the same as all other bikes or stick to an 8 speed chain.

    Chainring and sprocket on the Day One are obv 3/32" so I know some of you will say a 3/32" chain will run better but most of my other bikes have a 3/32" cog at at least one end and I don't have any complaints of how they run.

    TLDR: 1/8" or 3/32" chain for singlespeed?

  • I can't see any advantage in having the same chain on all your bikes.

    A standard roller (bushed) chain would be preferable to a bushingless chain though.

    However there aren't many bushed chains made nowadays. There's the Connex 7R8 (3/32", 1R8 is 1/8") and KMC B1 (1/8"). I'm sure if you roused Tstr from hibernation he could tell you others.

    Having said that, apparently you're still living so I suppose it's fair to say that while one is technically better than the other, it's not critical. Personally, I'd choose a bushed chain, over matching the width to the sprockets (the 7R8 is "nice but pricey", the B1 is very reasonable).

    TLDR: whatevs.

  • Only advantage in having 510s on all my bikes would be that I currently carry 2x 8 speed split links, 2x 1/8"split links and a couple spare links of each chain in my tool roll.

    Also I have cdo so it'd be nice to have everything on the same chain.
