We were curious how much of a difference the new chiseled design and the elastomer bands made to quiet the notoriously noisy (but oh so wonderfully light) SRAM Red cassette. On my first ride, the noise reduction was obvious. Now, thanks to Parlee, we’ve got a road bike in the test stable with the full group for long term testing. Surprisingly, the video didn’t pick up the same noise reduction as is evident when riding, but the change in pitch is. Perhaps that’s what makes it seem quieter?
I suspect it would be much quieter in shifting, the old Red cassette sounded like a tin cannon every time I dropped a gear. Another aspect is that perhaps the new design is naturally more quiet, but they added the elastomer bands to make it even quieter and also to show the consumer that the issue has been noted and addressed.
@Bikerumor – I’ve read that the elastic bands are replaceable… Can the bands be retrofitted?
the damping funktion is only provided within the impact area when the chain engages. The chain rollers only hit the right spot when load is applied and so the chain has a defined position on the cog. Try the same test with a little braking…

It doesn’t matter what sound it makes. Dunning-Kruger Effect. Go ride your bike and stop talking about them
