Driveline noise
 

Posting this question here because I dont know who else to ask...

I have 2 bikes, both have sram omniums, dura ace 53t chainrings, dura ace 16t cogs, one has a did daido chain, the other a izumi v super toughness.

My question is how much driveline noise should this be making? Both bikes make a contestant clicking (similar to a dry chain but both are freshly lubed) on the stand, riding, sprinting, recovery, basically same sound all the time. I assume that the chainline must be off a tad due to the omniums but since there's no way to adjust I'm stuck. Anyone have similar noise? I only ask because all this time I've heard how ninja silent njs set ups are. Btw it feels ok physically, just want to be sure I'm not losing power/speed due to drag or something. Should I just live with it?

First check to make sure the chain is not too tight but if it sounds like this - http://www.flickr.com/photos/pixelga...in/photostream

Its normal.

How's your chain tension?

There is no set amount of noise a drivetrain should or shouldn't make. Even if you have the same exact components on two different frames, some frames resonate sound more than others.

Typically if your drivetrain is making a lot of noise and your chainline is pretty straight - especially if it is clicking - your chain is much too tight.

it sounds just like that. its just odd because i have a spare kmc indx chain and if i use it it runs quieter. i know the did/izumi chains are stronger so i run them but that noise is bothersome. guess if others have that sme noise then ill just love with it.

just to fuel the fire. my chain tension is set at 1/4-1/2 of vertical play (if you use your finger to lift the chain from its static point). the d.a. chainring/cog/did are used, the izumi chain is brand new. i hear that d.a. components make more noise after use. a friend is running sram omniums/sugino sen/eai cog/izumi super toughness and has the same noise on a kagero.

Your chain is too tight.

what is the correct chain tension?

More than a quarter inch.

There's nothing really wrong with a loose chain... Go for like .5"-.75" of slack. Then let me know if it is still making a lot of noise.

Added some slack, went from 1/4" to 1/2" to 3/4" to a way loose 1" with the noise still present. Went the opposite way to see and while it got quieter it also didn't spin as well. Guess ill live with it or go back to the kmc indx

Although there has been much argument about it here, some cogs produce more noise than others. In my experience, DA cogs are pretty loud.

Also, your bike will always be louder while in the work stand (or upside down) than while riding.

I hear the same about DA cogs. Yes it is louder when I'm not riding it but I can still hear it on the road. Guess I was expecting more from a njs setup. Least I know it's not just my bike

NJS means nothing. Stop thinking it does.

Your bike is always going to make noise because physics.

I was posting a question and looking for info. I didn't ask or want the attitude so **** off

This.

It's a bunch of metal parts moving very quickly against one another.

Thanks for the help. I listened to the hype more then I should. Thanks again for the help without added opinions.

Dude you got plenty of decent advice. Seau is messing around. Chill.

Drivetrain noise happens with plenty of bikes, no matter how much their price tag/component gimmick etc. Once you get over this and stop noticing the noise, you'll start enjoying your rides more.

You could also wear ear-muffs, play dubstep while riding, or yell at the bike until it stops making noise.

What is it with people on the internet lately? They have the thinnest skin.

I guffawed.

That's a word not used nearly enough.

NJS is a racing bike standard, not a luxury car standard. :thumb:
