SRAM Drivetrain

i'm new to SRAM. I built my bike using 2010 force with PC1070 chain and PG1070 cassette. it's clean, properly adjusted and lubricated, but it's kind of noisy.

i'm not talking about the the clunk noise when shifting because i like that, it's positive and similar to campy, which is what i've always used, but rather the kind of rattling noise when pedaling along.

any other SRAM users note similar or am i being overly picky?

sorry for the 41-ish nature of this post, but let's be real, i'll get a better sampling of responses here.

Yes. SRAM chains perform horribly on SRAM 10 drivetrains. The best alternative that I have found is running a KMC DX10 chain. MUCH quieter. That's why I always have a stack of them (about 20 right now).

SRAM is noisy. A KMC chain helps.

Yeah I fell the same way, am told SRAM chains are crap. I just got a new DA chain, will try that. A teammate recommended the KMC, sorry Psimet that I did not see your response first.

I run shimano cassettes and chains on with my sram shifting for a reason.

With the exception of a Red 11-26 cassette I use for the more epic road races, when I couldn't possibly care less if it's slightly noisy.

I just talked to a guy that sprayed foam in the cassette and he said it didn't do much of anything. That was on the Red. He took it all off and put Shimano on.

I've seen the opposite. CX guys were using spray foam to keep the mud out and it was much quieter. Fill it with spray foam, put the cap on then trim the excess.

On my road setup I still prefer campy record chains.

I don't use SRAM but I frequently notice my riding buddies' noisy SRAM drivetrains. So much rattling.

all the moving parts of my drivetrain are sram: truvativ crankset, pc1070 chain and pg1070 cassette. the derailleurs are ultegras. my drivetrain makes almost no noise (which i assume has more to do with the hub than the drivetrain). on the other hand, i wouldn't mind if my hubs sound like a swarm of hornets.

I had the same rattling noise when my SRAM drivetrain was new, but it got quieter after a few weeks. I think the new cassette was the culprit. I've subsequently put on different SRAM and Shimano chains without having the rattle return.
