Another thread about SRAM's new 12-28 cassette offerings had me thinking that this might be a good thing to throw onto one of my bikes.

However, I do recall that ppl used to complain about noise, noisy shifting, and other issues with SRAM 'settes a year or two ago. Plus the knock that they maybe don't shift quite as well as Shimano.

So, Q: Have SRAM cassettes gotten better since then/dealt with the issues? :idea:

Inquiring minds wish to know.

never was a problem with the cassette - the issues have been about their chains. Lots of people, including some protour teams, prefer a shimano chain (not the new 7900 but 7801) with SRAM cassette/crank

I seem to recall many of the noise complaints centering on the SRAM "Red" cassette...since it is hollow, it allows sounds to resonate from within like a bell. If you're not using a Red, things may be quieter.

I put my first SRAM cassette on this year. I tried one on my mountain bike three years ago and it lasted about 80 miles before it bent. Now I use XT on my mountain bike up until this year. SRAM sent me a cassette to test and thus far it's taken six MTB races with zero issues. So I put one on my road bike. So it seems they've improved, but time will tell.

Thanks for that heads-up. After reading this, I do now remember others also talking about the 'resonance' issue with some SRAM 'settes a year or two bacik.

Get a KMC X10 chain to go with it and it will be great!

All the problems I had went away when I got rid of the SRAM chain.... and IMHO the KMC is better again than a Shimano chain. :thumbsup:

Shimano chains are horrible for mountain biking, and I think the XTR chain is same as Dura Ace. I've snapped so many of them that those chains don't even register on my radar anymore. I put SRAM chain on my road bike just because I trust SRAM chains. I've only broken one SRAM chain compared to countless Shimano (all mountain biking).

Maybe Shimano works better on road bikes.

Don't know much about KMC chains.

For chains, the XTR/DA 9 spd mtb sucks. I've broken two. Both not in races but just doing regular MTB.

SRAM MTB chains with the powerlink just hold stronger under torque than inserted pins. Sure, I probably should shift better/faster to lessen the torque, but sometimes you forget and rapid rise can't even help you there.

Shimano for road. SRAM for mtb.

RED cassettes are noisy and always will be with any brand chain. NEXT!

I've had a SRAM Cassette on my bike for the last few years and it's been noisy from day one. It shifts fine and i've gotten good life out of it, but the noise when freewheeling is annoying. Just bought a new ultegra cassette, changing it out tomorrow.

It hink here its the difference between the PG cassettes and the OG cassettes. I have read more people had problems with the OG and I dont think SRAM is making them anymore.

Correct the issue was with the OG cassettes. The new PG (power glide) cassettes are much quieter.

The SRAM cassettes are ok, and like others have said it's only the red that's noisy. However, a Shimano cassette will still shift quicker. It's not like the SRAM is junk though.

On SRAM's website, it shows all its groups (including Apex) now using PG cassettes... except for Red. :eek:

"retired" OG-1070 + 5600

Most I can complain about is violent shifting, but everything's sure-fire and it's not posing as something detrimental to my riding performance...so the cassette is staying. If anything, I think SRAM should attempt a Red-derived update of the OG-1070. Three largest cogs lack the "missing" sections, which I believe contributes to an even more violent shift from the 3rd to 4th gear.


But yeah, regardless, there's no real, functional problem. I can shift supra-Andy Schleck :p

I'm running the PG1070 cassette with a DA 7801 chain. I do get some noise...especially in the three larger cogs. I don't mind the noise though...

I'm running a PG1070 cassette with the PC1071 chain. Its pretty quiet.

On my MTB's (which I race) running Sram PG980 cassettes with Shimano XTR/DA chains. No issues with chain breakage. I was running a Sram PC991 chain for 2 years without issue, and heard that the XTR/DA chain shifted a little smoother with the Sram cassette/shifters/derailleurs. I don't notice any difference IME. Maybe next chain will be another XTR, or it might be a PC991 again.
