Re: BoyGoFast 415h chain, anybody bought one?
The Z410 is standard duty. It's basic chain, albeit KMC quality. I'd expect it to be better than any kit 410, or for that matter, 410 that's available at Walmart - like Bell.
But it's still basic chain. I've seen Z410 at SBP for $6.50 and 410H at bike shops for $9. I just paid $23 for 2 boxes of 510HX at Amazon with free shipping.
If you're using it for engine power, I'd go with 410H at least. But that's just my opinion, I tend to lean towards overkill when it comes to cables and chain lol
