|can a cheap chainring cause a noisy drivetrain||DERICK|

|I recently purchased used bike with a full Dura Ace group. The bike is a 2000 model.Apon close inspection I found that the large chainring is a Blackspire (made in canada).I have never heard of this company.
Anyway, I have been noticing a lot of extra noise when using the big ring. The chain is not touching anything and I keep the bike very clean and well tuned. I just put a new DA chain and DA casette on it to get the gearing I wanted so everything else is new. The noise is not really bad, sounds like regular bicycle noise only louder.
Any advice or info on Blackspire would be appreciated

|Don't know about that exact product, but the answer to your question is yes - if the patten part is not machined to the same spec/tollerances as the "real" one, then there will be an amount of mis-meshing as the chain passes round the ring, which will cause noise, and most likely, wear problems too (though they may be too small to make and real difference).|

|My '99 Klein QR exhibits drive train noise when I am in certain gears. It drove me nuts for a while. Upon close inspection I noticed that I had slightly tweaked the large chain ring when I took a minor tumble when my bike was fairly new. It's hardly visible, just a slight wobble, but enough to knock it out of alignment. Just a thought...|

I recently purchased a new PINARELLO with full Dura-Ace 9 speed.But I also use SPECALTIES TA chainrings,which are cheaper than Dura-Ace.Also because then come in different number teeth,and my drivetrain sounds exactly the same.
Hope this is a help to you,
