The bottoms of both track ends have bent inwards... what's up with that?

I dropped my bare track frame on the garage floor once.

You know, banging s**t with your hammer does do that!


What did you do to it?

I just shredded my finger trying to figure out what the chain noise was
After I stop gushing blood, maybe you all can help... there's no noise at all when the chain is off, and the chainline is dead on. It makes the noise whether the chain is too tight, too loose, or perfect. The noise is coming from the engagement of the chain on the sprockets, especially the rear.
I'm gonna go cry now...

Btw, brand new chain, and everything's clean

lacklust-

I'm having the exact same problem...and my chain, as wel as my chainring and rear cog are all brand new... I think it's just that chain is new...I have to have bb looked at today or tomorrow, so I'll let you know what they say regarding chain noise.

lacklust? hah!

I got the same noise with the old chain as I do with the new.

did you put your frame in the dryer on "high heat?" Chromed steel requires a delicate cycle.

perhaps its just the sound of the chain engaging with the sprocket teeth???

Lubing with plasma and dermis probably isn't the answer.

I have a new SRAM 1/8th chain running on a new EAI 1/8th cog with a perfect chainline. If I listen carefully there's a rhythmic engagement noise that alters slightly as the rear wheel rotates. Just needs to run in a bit.

Unless the noise is very loud I wouldn't worry too much. It's a machine, don't you know?

perhaps the rear cog isn't exactly true, and a varying tension throughout a revolution is causing some off noises? try checking your chain tension at various points, using the location of your pedals as a gauge (easier to do accurately if you have an even/even ratio). i've found that my chainring is sorta elliptical, and i've attributed my drivetrain clatter to the variance between a wee bit tight and a wee bit loose that occurs ever 2 seconds. just a thought.

It's really loud. I'm usually wearing headphones (yeah, I know) so it doesn't bug me, but it's waaaay louder than my Peugeot.
