    SS chains the only way to go?

    are SS chains the only way to go with a single speed?

    If so, why? Other chains can't take the amount of torque? Will they either break or fall off?

    If not, what kind of chain are you running?

    I have had terrible luck with all of the SS chains I have tried. I have been running SRAM 8 speed chains for several years and have had really really good luck with them (and they are pretty cheap)

    Not sure if it is.

    z-72... is that a SS chain?

    z72...
    it's an inexpensive 8-speed chain
    I keep getting them because they're cheap and I dont break them (I don't break other brands either so...)
    they shift fine on my gearie too (side note - if it matters)
    Honestly... ahh I give up

    i run the full nickel plated sram 9spd chain on my old single speed, that way if I do happen to break a chain (happened once long ago on a severely worn chain) I can steal a few links from a geared riding buddies chain to limp home.

    +1 for Sram 8-speed chains.

    KMC Z610HX SS chain is nice, but the master links sucks.
    Ride more!

    Is that personal? You can read that on any of the bimonthly threads about what chain to use. Have you noticed this is an internet forum?

    Tom- which model do you usually run? Which chainrings and cogs (out of curiosity)?

    I've been looking for something outside of the few 1spd chains that are on the market.

    SRAM 8-spd stuff is really strong and you will likely never have a problem with it. Scooter916 has a good point, but if you carry a couple links of your own, then you are rocking regardless of what chain you ride and if you are solo too! I run SS chain (1/8" vs. 3/32") only because the cogs and ring teeth are wider and will last a lot longer, if made of comparable materials...

    The torque is potentially the same, just way more often on a SS. On a geared bike, when you shift down, you're sparing your legs, and the drivetrain that "max force" load. On a single speed, you don't have that option, so things wear out faster.

    Maybe it's just my imagination but my Surly ring seemed to get wedged in between 9-sp chain plates, maybe because 9-sp is narrower? I'm on 8-sp Sach chain from the 90s that came off an old bike. No issue for 9 months now.

    Yep, 9spd chains are narrower. Surly only rates their MTB rings for 8spd chains (see here)

    SRAM 8spd chain for me.

    If a half link is needed, then it's the Gusset half link with a pair of KMC Z610HX-C/L master links. Stay away from the KMC half links as they're more trouble than they're worth.

    SRAM 8-speed. I also carry a spare SRAM masterlink and a lightweight chain tool. I have never needed it for myself, but have bailed buddies who broke their chain on their deraileur bikes.

    Funny... the only chain I've ever snapped was a SRAM PC-58 8 speed chain. 32x22 gearing and a pedal kick... SNAP.

    Never again will I buy a SRAM multi-speed chain. If I can't trust it, it doesn't go on the bike.

    I am a total sram hater but even I have to admit that the 870 is a great SS chain. Is it just me or are the Sram 9spd chains way over priced? Doesn't the 971 look just like a slightly narrower 870. Only the 870 is way cheaper. Infact shouldn't the 9speed be cheaper since there is less metal there. Maybe they actually discounted the 870 but I doubt it since its more likely that they just make more money on the 971.

    what's a single speed chain?

    i've been using cheap kmc chains the last 10 years that come in the red or blue box and cost about $7.95 and last about 2-3 years before it breaks or stretches too much. don't know if it's a 6,7, or 8 speed chain or what model number, just that if the box color matches the price, i'm good.
    will you rep me?

    6,7,8 speed chains all be the same 3/32 width. A true single speed chain is a real fat 1/8".

    A true single speed chain is simply one with straight plates. BMX bikes use 1/8" chains, there's no reason to use one on a mountain bike.

    and don't mix rings and cogs designed for a 3/32 chain with a 1/8 chain. Even with perfect chainline and tension it will come off, well, at least that was my experience.

    ran it like that for years without dropping a chain once.
    not the best idea but it was a free chain and i like free stuff.

    i have used a 3/32 fixed gear setup on my commuter with a kmc 9spd chain for years now, and never had a single issue. i'm pretty rough on that chain too. i'm 200lbs, and i skid/skip all over the place.

    Good job!

    I'm still utilizing my old stash of SRAM PC7X chains....the gold color is long gone from the sideplates on all four SS bikes.

    These were supposedly reintroduced?

    At 6'5" and 240, I tend to break the 8spd. SRAM chains mentioned. I'm really rough on the PC7X's, all four are >5 years old, now.

    Anyone else have more trouble with their cogs/chainring teeth getting splayed/worn than with chains breaking? I've never broken a chain on a SS but go through chainrings/cogs way too often.

    I had the same problem until I reliazed that i was running my chain a little too loose, once i started running the chain tighter my cogs and chainrings started to last way way longer than before

    Regular 9 speed chains with a powerlink. I'm pretty weak though...

    Edit: 8 speed work fine too and are a little cheaper, a little heavier.

    Glad someone started this. Been converting an old Diamondback Sorrento to SS. Got a DMR tensioner and had gotten a singlespeed chain. Then it says on the packaging that you should use a 8 or 9 speed chain with it. Huh? Well, maybe that's the case, because have not been able to get that thing to work properly at all the minute you put any kind of tension on the chain. The tensioner flexes something fierce. Any ideas?

    I haven't use that specific brand of tensioner, but with those roller style tensioners a true 1/8" singlespeed chain could be wide enough to bind against the sides of the roller. Also make sure you have a good straight chainline from the front to the back and that the tensioner is properly lined up with that chainline.

    If that isn't it, just tighten the derailleur hanger bolt harder

    The only chains I've broken were using improper links. (AKA the "hammer an old pin in to add a link the night before a ride" method.) I broke that one running 32/20 on a 26", meaning not a lot of torque.

    Other that that, 32/18 on a 29er running a 9 spd SRAM. Its plenty strong for hammering up steep stuff, and stronger riders than I do the same. Take care of your chain and it will take care of you.

    I would not judge a chain on the first couple of rides. Using an EBB, I notice a chain will lengthen quite a bit the first time it is used; this may be due to the factory lube being forced out of the chain. OTOH this mtbr reviewer seems to agree with you..

    Favorite Trail: Swiss Wall Morzine
    Duration Product Used: 3 months

    Purchased At: CRC
    Strengths: Can be used as a door stop afterwards. Highlights of my time using it included removing it from my bike for good.
    Weaknesses: Incredibly weak construction. Wears faster than any chain I've seen in my short lifetime - mine was destroyed in just over three months. Once it's worn, it will destroy your other components. My bike doesn't even have a deurallier and it's still bad!
    Similar Products Used: SRAM PC 850, PC 58, PC88.
    Bike Setup: Ibis Mojo with Rohloff rear hub, 44 tooth LX ring.
    Bottom Line: Just pay the extra for one of SRAM's better chains and you will definitely save money in the long run. This one just isn't built to last. Not only does it wear quickly, individual links break down into pieces, and the whole chain will then quickly wear your other components.
