Chain

So I ordered my new SRAM pc-58 chain and I was sent a pc-850. Is this the updated model of the same chain or did I get screwed?

Any reason you're in the ssfg forum wondering about an 8 speed chain? Try the mechanics subforum yet?

everything I have read says the pc-58 is a great fixed gear chain. Am I wrong?

I use a pc-850 on two of my geared bikes. I'm sure it will work fine on your fixed gear as long as you have a 3/32" chainring and cog.

I'm sure it's fine. Unless you're racing, whatever fits (1/8 or 3/32) will work fine. Every LBS you go to has a preferred vendor and will sell you there's swearing it's the best. Don't sweat it too much, just buy a chain and ride.

I know you want better advice all about the most badass chain, but there isn't one. Just opinions. Most folks on here use cheap KMC chains.

Any *speed chain will work on a fixed gear assuming you have 3/32 everything.

A 58 sells from 13-20. An 850 for 16. Can't get too upset.

I'm guessing you got NOS. The 58 is on their product site. the 850 is just a cassette on there.

Ok... offical word about SRAM parts:

Last year SRAM realized they'd grown big enough that the two character two number (XX-00) designation wasn't going to work if they wanted to expand any of their part lines. So, for example, a PC-58 chain is now a PC-850. The 8 designator is the maximum number of gears that the chain is compatible with and the 50 (or 40, or 60 etc) is a designator of the quality level of the chain.

So... no you didn't get ripped off. Just confused.

So you won't see PC-58 or PC-59 (ha! 9 speed!) any more. Or rather, they're not labling them that way any more, some shops (mine included) still have some of the old designator chains in stock. Though, honestly the new system does make more sense.

Chains only break in order of likelihood

1) User error when installing
2) Worn out
3) External damage
4) Manufacturing defect

With #1 taking about 90% of the cases out there. Much harder to eff up #1 with modern chains and quick-links.

Interesting info Severian, I wondered but never hesitated on using the 850 chains. I've sworn by the PC-48 in regard to bang for buck and so far no different for the 850s I'm using.

thank you so much for your help. I figured this was prob. the situation but just wanted to be sure. Thanks again.

the 48 IS an excellent chain. The benefit you get from the 58 is slightly lighter construction overall, and slightly tighter tolerances (less slop).

Basically if you lay a slack piece of 48 and a piece of 850 (or 58) of the same length next to eachother you'll be able to deflect the 48 just a bit more... errm... to be clear that's if you lay the chain down w/ the rollers vertical.

Sinvoz, do the side plates bow outwards a little bit, or are they perfectly straight? On the PC-n8 series they used to be straight, but I saw a photo of the PC-8n0 series and they appeared to have that bowed out section.

The PC-n8 series chains were by far my favorite. They were silent with an EAI cog, durable, cleanable, and they came with a masterlink. I hope the new series is exactly the same, because it's about time for me to be replacing mine.

It's a good chain up until you start riding in rain/snow/slush all day. Then it ****ing blows. But to be fair, so would any other non stainless-steel chain.

True, but at 20 bux or less a chain you can afford to toss em as needed if you choose to ride in conditions that are detrimental to a plain steel chain.
