Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

3/32

according the business cycles you should not use a multi-speed 3/32 chain on track cogs.

what are my 3/32 track chain options? does Izumi make one this size? if so, where can i find one? it seems KMC bmx chains are the best bet otherwise.

why shouldnt you use a multi-speed chain with track cogs?

Aren't "track" cogs 1/8th inch? I'm assuming the OP meant that it's not OK to use a 3/32" chain with an 1/8" cog.

multi-speed chains need to be more flexible, left and right, since they get derailed by derailuers i think.

not sure about cogs, but there are chainrings in 3/32... assumedly, there are also track cogs in 3/32. i think business cycles was warning against busting out a multi-speed or "road" chain on a track/fixed set up -- which makes some sense.

you can have either a 3/32 or 1/8 track drivetrain. you can use a 1/8 chain with either or a 3/32 with the 3/32 but not on the 1/8.

bollocks.
8-speed chains are fine.

if you're talkin 9 or 10-speed OTOH, you may have an argument

i'd rather ride a chain that is supposedly designed to spin straight without flex to the right and to the left if it costs about the same. might as well, ya know?

I ran crappy old sedis 7-sp chains for a few years before I knew any better. I didn't die.

i've got a 3/32 drivetrain. my chainring is an older sugino (also have a backup campy), the rear cogs i have are EAI, they are all 3/32. its been a ***** to find a 3/32 track chain locally. i've had to settle for an 8 speed KMC. it works fine, but i think the izumi may be stiffer. since it is track specific, it will likely have a better life on my drivetrain.

thanks for the soma link.

There is no problem using a 3/32 chain on fixed gear bikes. They're no weaker just because they can flex to the side more. I swear I've seen Sheldon (and others) discuss this exact topic. Ask how many people have snapped their 3/32 chains from regular use.

I wasn't aware they even made 3/32 track chains, which is why I assumed that "track" drivetrain parts are all 1/8. That's what I get for assuming.

Sheldon talks about it and specifically recommends not using 1/8" drivetrains because the technology, competition etc for normal narrow chains makes them likely to have better manufacturing standards and less expensive, in addition to being lighter and 1/8" offering no advantage because of its width.

The only reason to run 1/8 chain is because the cog or whatever you have laying around is 1/8. 3/32 isn't stronger, and the flexing as for shifting thing is a red herring. Pick up a 1/8 chain, it easily flexes side to side as much as it ever would on a single speed drive train; if you're going to throw your chain, it's going to happen regardless of whether you're running track chain.

On a single speed/fixed with a decent chain line, the only force on the chain will be straight down the center. The chain won't flex right to left.

Also, the thickness of the metal of each link will probably be the same on either a 1/8th chain or a 3/32. I don't think there will be a difference in strenght, all other things being equal.

3/32" multi speed chains probably are stronger. I don't care how burly you are, those chains deal with way more torque on the small ring of a triple crank than you can throw at it on a fixed no matter what the gear ratio is.

I have a 3/32nd on my spare bike. You can't tell the difference when riding. I don't think the chain was that much different in price from a 1/8th.

Some gear teeth are too long to use 3/32. I use Miche quick change cogs, and 1/8th is the
only size that will fit those

Folks, 1/8" chain is way heavier. There's no way I'd run that when I could just have a 3/32" drivetrain and save 20 grams. Unless it's Ti...

Nope- i really do mean teeth 'too long'. I had a multi-speed style chain, and you couldnt wrap the chain around more than about 3 teeth. Past that the teeth were too long. The singlespeed chains have a bit more space to accomodate the longer teeth.

WRONG. It sounds like the chain you have was stretched. Each link is 1", 1/2" pin to pin* regardless of the original purpose.

*Unless it's inch-pitch or Dura-Ace 10mm.

The chain was brand new- I had to return it for a singlespeed style chain
