    Need tech/wrenching help !

    So last winter i purchased a Santa Cruz Jackal. I bought it to use for pumptracks and jump parks and such, and it's been great.

    It came setup with 18x36. The bike has sliding dropouts. The chain on the bike was different, i'm guessing it's a 3/32nd BMX chain based on my limited knowledge. I been trying to swap from 18t cog to 14t but working with this particular chain has been difficult and hard on my chain tool.

    So here's my question - i'd like to get the bike running for this weekend, am i safe to run a regular 8/9 speed SRAM chain.....?.....the cog is a Shimano MX66 and the crank/chainring is Shimano Zee.

    Thanks.

    Yep that should work! My 16t is a MX66 and im using a 10sp chain on that.
    Zee is a 10sp drivetrain so no worries there.
    I would rather use 8/9 due to cost.

    Thanks.

    I just ordered a SRAM PC1.
    Didn't know they made such a thing.

    PC1 is a wide bmx/ beach cruiser singlespeed chain. There's no reason to run one of those on a drivetrain make with 10 speed chains in mind. If you need a burly, strong singlespeed specific chain, a KMC z610hx might be better. Most of us run SRAM 850 chains because they are sufficiently strong and cheap.

    SRAM PC-1 Single Speed Chain | Jenson USA

    "For 1/8" single speed specific cogs and chainrings only. Do NOT use on drivetrains designed for use with multi-speed 3/32" chains."

    You have narrower cogs making the chain way to wide. It will work, but won't be the most durable solution compared to a 8/9/10sp chain.

    The sram 850 didnt last for me, rusted easily and the only chain i've broken while ridng (may have scrubbed some rocks) The xx1 was fabulously durable but too expensive.

    I've been really happy with the kmc 10.93, $18.55 on Amazon, quick link and nickle plated.

    In my experience the PC-1 is the worst chain that Iíve ever used. The KMC Z-610HX is far superior.
