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)

how quiet are your fixies?

i keep reading and hearing how "whisper quiet" everyones fixed bikes are. is there something wrong with mine? i am running a 42 zen messenger ring with a kmc 410 1/8th chain to a 16 tooth dura-ace 1/8th cog. it feels super smooth, and it all looks pretty darn straight - just not that quiet. sounds like my 20" bmx bike. lots of chain spinning noise.

I haven't quite gotten around to purchasing one yet, but I suspect it will likely be a Soma Rush model.

Try a better chain, KMC 410 is ok stuff but the rest of your drive train is way classier than that.

Some drivetrains are just loud, especially when new.

Mine's pretty loud too, despite a perfectly straight chainline and my best attempts to keep the chain clean and lubed. I think it's either the cheap KMC chain or the Surly cog. Or both.

Mine was quiet until I switched from the factory 16T cog to a Surly 19T. Now it sounds like a coffee grinder. Louder the harder I pedal, it seems. Izumi ESH chain.

I think it does have something to do with the Surly cog, mine was loud as hell when I first got it

mine is also a little bit louder than i want it to be. I've been blaming my heavy duty z-chain, but maybe it is the rear cog (or the suntour one piece cranks, ugh)

When I built mine, I used regular SRAM 8-9 sp chain because that's what I had on hand. It's always stealthy quiet as long as the tension is right. That was the first thing that really grabbed my attention was the silence of it. So much so that I went to great measures tracking down and then silencing the slight rattling caused by the cable-less brake lever on the right side.

Chain makes a big diff. I switched from a cheap KMC to a nicer SRAM (P58), and things got quieter.
Still not silent, but not a problem.

i've found that cog makes a bigger difference than chain. my surly cog is noisey, my DA cog is not. not a wide net of experience, but still.

sometimes it has to do with the chain being too tight, or just not lubed up... put a little bit of lube on there and be sure to remove the excess.

Some set ups are just loud, there are a lot of factors, frame, ring, cog, chain, etc

My Steel track bike, with an Izumi ESH chain, Campagnolo chainring, and Campagnolo cog, is quite loud. I've noticed that most bikes in the Velodrome are loud, maybe its the gear combination, or surface of the track amplifying sounds.

My conversion, which once had a jacked chainline, a cheap SRAM pc-1, and 20 year old sakae ringyo chainring, and a surly cog, was dead silent.

My current set up on that bike is a miche ring, eai cog, and a izumi ESH, pretty quiet, but not "silent"

I just replaced my KMC Z/H chain with another Z/H. It went from quiet to loud, but the previous chain started off loud too. I think that's partly just the nature of a new drivetrain; as everything gets worn into each other it'll get quieter.

One thing about new chains.... The cosmoline used on new chains is not lubricant, it's rust preventative and attracts dirt like a b!tch. New chains should be thoroughly cleaned to remove the cosmoline and then lubed properly with your chain lube of choice. Maybe this is a "duh" statement and not applicable to the noisy drivetrain issues being dealt with here. I just thought it worth mentioning.

my drivetrain is a little louder than i'd like right now, but i have no money to fix it. i think it's my chain (KMC Z chain) because my cogs and chainring are both quality (sugino 75 lockring, eai/da cogs).
