I have recently started to get anoyed at the amount of noise my Giant Reign produces in the rough. i run the stock chainstay protector on the chainstay made of molded rubber and a aditional thin strip on the lower end of the seatstay.

do you guys have any ideas on materials or hacks that might further reduce the noise? i would like to maintain the sleek look but would sacifice design for funktion.

do you have a clutched derailleur and NW chainring?

well lubed XT M8000 clutch with proper tension and chainlength. NW ring and MRP upper chainguide. all standard solutions seem exhausted.

Today i tried to glue down every mm² of the rubber chainstay protector is now glued down lets see if that helped, although it was pertty solid before hand

I've seen people use the "loop" side of hook-n-loop fasteners to help quiet chain slap.

Check out the new stump jumper... there's a video or article floating around about how they used high speed camera's to watch the chain. Realized it did some kind of wave motion and designed the stay protector around that to quiet the noise. Supposedly it works very well. Kinda just looks like they added some bumps in strategic spots... have heard of some guys using chunks of tire or tubes to mimic the design with good results.

You can see it pretty well towards the end of this video

If you wonder what they used in the (edit) GMBN video, it's most likely some 3M 2228 (exactly the same as the Marsh slapper tape, but cheaper). Bought a big roll off Amazon a while back, still got some and I put some on all of my bikes. I might experience those little bumps to quieten the bike I currently have, which isn't as silent as the previous one.

I also use 3M 2228, works great!
