Normal chain noise????????
 

I just bought a fixie from a friend and the components are almost new and the chainline is right on. However, when I have the bike on the stand and spin the pedals the chain makes a noise at the rear cog. It is a fast clicking or vibrating sound (don't know how else to describe it). Is this normal********** Any help would be greatly appreciated.

Chain tension too tight?

is it an 1/8" chain?

if so its pretty much normal.

It makes it at any chain tension and all components including the chian are 3/32. Should I try a 1/8" chain

Just keepin' this at the top, since I'm wondering the same thing.

My bike always has noise when on the stand--it should go away on the street. If not, clean and lube your chain. Dirty chains = noise in drive train

also, crummy cogs make for loud noise. Look at the teeth and see how smooth the edges are. Thats where alot of noise comes from.

mine makes a constant noise that gets a lot worse when the chain is real tight. its not quite a clicking, but its hard to explain otherwise. i've chalked it up to a ****ty hub. im getting new wheels soon, so i'll see if that helps.

seriously, a ton of chain noise is attributable to a dirty chain

Lube that b*tch up and ride HER like it's the last hour of your life!!!!!!!!!!!!!!!!!!!!1111111111111

Chainrings being not perfectly round causes chain tension to be high (or correct) in most of the revolution and loose in the rest. When the chain tension loosens (at high revolutions) the chain will oscillate, causing some of the noise. Put your bike in the stand and pedal at about 60 rpm and watch to see the chain vibrating. It's like if you stretched out a rubber band and plucked it. If so, get a new chainring (or just deal with it).

This is, of course, after you clean the **** out of your chain and lube it back up.

This happens when my chain is at its tightest and I don't notice it when on the road.

Just ride the damn thing and see if the noise is audible while riding, when everything is already worn in and lubed.
