    Expensive chains are the only ones worth buying

    Oh wait, the aussie national team uses a $25 bmx chain. KMC K710-SL






    ::sits back and waits for people to claim that street riding puts more stress on a chain::

    *edit: its $14.95 at ebikestop

    does the aussie national team keep their bikes in a laundromat? what are those machines??

    actually, putting a $110 HKK vertex was the first upgrade on my schwinn traveler conversion. i figured it would be necessary for all the time i was spending on the velodrome. next is a front aerospoke

    EDIT: I was the guy in the other forum to spot that chain

    I've been a fan of the KMC K710s for a few years. I thought that chain looked familiar when I saw that closeup photo.

    Many KMC singlespeed chains (including the one pictured above) are primarily designed for BMX racing. BMX pros can put more tension on their chains that track pros because they run a smaller chainring and use longer cranks. I use KMC 510HX (1/8") and 610HX (3/32") chains...never had a problem with them. They seem to last longer than other chains I have tried, including expensive NJS chains. People who criticize KMC chains are clueless. Stay away from the cheap 400 series chains. The 500, 600, and 700 series chains are strong and very reliable.

    I have been using the 710sl for over a year now and love it. A guy at a lbs tried to talk me out of buying saying it was only for racing but I use it on the street and it has been great. It stretches less than any of my previous chains and I figured for the 12 dollars I spent it was worth saving the weight (rotational weight at that) over other chains on the market. It's strong, it's light, and it's awesome.

    The 400 series chains are worthless. I used to swear by them, until one failed horribly.

    Word, I thought that this information was needed much more here.
    Especially because I recall a recent dialogue about how $80 chains are a wise investment.
    kudos for picking up on it first

    The K710 has a break force of like 3,000lbs. That's a lotta watttttts.

    They have an initial stretch during the first ride, but settle in nicely after that. They are awesome and easily available. Any bike shop that carries BMX parts will have some in stock.

    i don't get it. you had lots of good experiences and one bad? might the bad one have been an outlier? i don't usually start to distrust bike parts until i hear several stories of them failing which suggests a flaw in design or manufacturing. one failing could have been due to anything.

    Word.

    I don't like the $10 chains. But, this $25 one is the best I've seen. I can't see the others being 4X stronger or that much more quiet.

    What's more is that those are $20,000 bikes. Let me repeat that. $20,000. With a custom not-available-to-mere-humans rear wheel. I'm sure that every part has been scrutinized.

    Are those their training bikes? That crankset looks like one of those power measuring ones. If that is the case those could be their training chains. Do teams have training chains and different ones for race day?

    I use a $13 Miche chain and it works just fine for me. I couldn't really tell the difference between it and my $60 Izumi chain. Then again I'm no expert. There has to be a legitimate reason why certain chains are more expensive, I just don't know what it would be. Better performance, lubrication and manufacturing?

    Well one chain snapped while riding and had numerous cracked plates. Reason enough to not buy that model again.

    That's a SRM power meter. Riders use power meters in-race as well as for training. For a quick example here is Marcus Burghardt's (Columbia - HTC) file from one stage of the 2008 TDF: http://tour-de-france.velonews.com/article/80756

    does it defeat the purpose of getting a expensive chain if you have a mediocre cransket? I'm using the stock set on my 08 Bianchi Pista.

    The drivetrain is a system which is only as good as it's weakest link. Your stock crank arms, BB, chainring bolts, chainring, hub, cog, or lockring will fail long before a good chain will. A moderately strong rider riding a lot would probably break or stress one of those in no time.

    As discussed before in this thread, at a certain point (apparently $25 in this case) chains reach a point of diminishing returns. Sort of like Asparin where 10 does no more pain blocking than 2. Or caffeine where a large gives you no more benefit than a small (a longer benefit maybe, but not a bigger one).

    Hahaha.
    I think that front wheel is backwards. Definitely oriented opposite the rear isn't it?

    The more expensive chain at the LBS came in various colors. You sayin colors make my chain better?
