  • DID 520 ERT2 Gold Chain

    DID 520 ERT2 Gold Chain

    Greg in NS

    Great for small bore mx bike

    Very light, free turning chain. Great for a 125 mx bike because it doesn’t steal any of your power. Doesn’t last as long as a o-ring chain. Adjust after your first ride then try not to touch it again if you want it to last.

    DID 428 VX X-Ring Chain

    laecutter in TX

    DID chain

    Race mini quads with high performance engines. The 428 VX X chain more than holds up under the pressure and abuse these little quads dish out. No chain problems since switching grips the sprockets tight.

    Primary Drive 520 ORH Gold X-Ring Chain

    Carlos in CA

    You can pay more, but why?

    I just put this on so I am not sure how durable it is, but I flogged the bike around Hungry Valley, Ca for a 5 hours and it looks good. It sagged as a new chain does after a first flogging....I suspect it will hold up. We will see.
