Well I worked there.

I_luv_hooters

I've only had a 3/32 chain once. It was the only bike I've ever had with an absolutely silent drivetrain. I loved it. Now I've got sugino 75 and big 1/8 NJS chain. I sorta wish I had that cheaper quieter set up. I would do it again if there was a chainring in 144 BCD that was 3/32. That way I could keep my crankset. Is there a chainring like that?

barba

144 BCD is the old Campagnolo road standard. You can probably find some old road rings that will be 3/32". I think I have a few in the parts bin.

operator

Yeah, dura ace makes a 3/32 144bcd chainring. They obviously cost quite a bit though.

barba

Try this one, hooters. $26 shipped, 49t.

kidtwisty

What's the best tire for skidding?

patric

Whoa way to be a ****** ass canadian. you sound like a bigger ******* than me.
i bet you post thousands of witty reply's on forums about sex too, cause your definitly not a ****ing dork.

barba

What is your point, patric? He is right.

patric

yeah i know. i should probably delete that before i get another thread closed.

patric

just kidding operator. be more positive though..

i have like 9 million feet of 3/16 chain left over from selling road bike conversions.

xunchicrewx

the surly came with a 3/32 and i changed things over to a 1/8th(dont ask why!) and the only thing i notice is the 1/8 has more noise and it seems a bit thicker..but duh

a b seize

yes, it would seem a bit thicker. as you said, duh. anyway, are 1/8 chains really noiser? it makes sense if it is running on 3/32 components, but what about if it's on 1/8 components?

edit: this is probably in one of those 20 some threads posted earlier.

1/8th components on 1/8th chain ride like a dream

bonechilling

I've always road 1/8" on my track bikes, and I never felt like it was anything special. Spend a few hours at the velodrome listening to 1/8" chains grind away and rumble through disc wheels, and you'll be covering your ears.

blickblocks

I ride 1/8" only because it makes sense to me that it should last longer. Larger contact area = less force per square inch. On the other hand, this could also be achieved by using larger cogs and rings together, which I didn't do (started out 14x40).

Peedtm

^^^ that thick, big crap's too heavy. . .

c0urt

I have a 1/8th chain and small rings and cogs. loud but i dont mind really.

MrCjolsen

Am I the only person who likes the way the shiny KMC bmx chains look?

EivlEvo

All my chains are shiny.


I have a red KMC chain. Its perty.

Straws

I threw a chain on my conversion the other night and nearly **** my pants. i cant imagine doing that in traffic.

operator

lulz.

Tell your manager that you can order Shimano IG chains for below single digit prices.

patric

i rode like a week straight with my ipod on and in some rain.. chain was so loud when my battery died during a ride. gotta carry some lube with you.
oh and it was a 1/8 chain.

xunchicrewx

yea i did notice a difference but due to the winter i ride more on my trainer so i cant tell if the noise is coming from the trainer or the drive train.. or which is more prevalent.

BLACK BIKE

Since I am also no fan of misinformation, I must point out that this couldn't be more incorrect.

An 8 speed chain is best for an 8 speed drive train, while a single speed chain is optimized for a single speed system. Here are a couple of the key differences:

The side plates of modern multi-speed chains are beveled, while single speed chains lack this characteristic. This beveling facilitates smooth gear changes on a multispeed bicycle, but encourages chain throws on a single speed.

Single speed chains are lateraly stiffer than multi speed chains; they don't flex side to side nearly as much as a multi speed chain does. This lateral stifness also helps to maintain a straight chain line and prevent chain throws.

Try wrapping a single speed chain around the outermost chainring and the innermost cog on a MTB tripple, and you will see that these two types of chains are far from the same. You are confusing strength with flexibility.

If you you hold a quality 3/32 single speed chain (such as the KMC 610hx) side by side with a multi speed chain, you will easily be able to see and feel the difference.

BLACK BIKE

The only advantage of 1/8 is that you will have a greater selection of track specific chainrings. There is no evidence to support 1/8 being stronger than 3/32. People who complain of reliability issues with 3/32 chains on a single speed or fixed gear often use the wrong chain (8 speed chain). The KMC 610HX is the best single speed 3/32 chain, bar none. Don't confuse this with the cheaper KMC chains. These are bushingless and surprisingly quiet. You will have no problems with a 610 and at $15 it's a steal!
